MonsGeek - FUN60 Ultra TMR/HE

Attack Shark has been fraudulently advertising their proprietary firmware as QMK so I wouldn't trust them. If you want a magnetic board the Monsgeek TMR boards have more sensitive sensors than the typical HE ones. That would be the M1 v5 TMR and Fun60 Ultra TMR. If you want conventional switches, QMK firmware is best-in-class, and the VIA and VIAL configurators are less restrictive than any proprietary drivers. I have a list of VIA-compatible boars on my [Github](https://github.com/ArgentStonecutter/keyboards/blob/main/via-boards.md)...

Well 2 months ago I did, but I have seen some complaints since about the magnetic board software from Monsgeek. I don't recall the details, but I would do some research and see if there are any blockers. The Monsgeek hardware itself is solid as a rock.

Unless you play something like osu the difference is pretty minimal. If you want to go with something that's technically the best then go magnetic, but it's honestly a nonissue either way. If you want to go magnetic something like the fun60 Ultra tmr would be a decent budget pick. It uses tmr switches rather than he, but it can actually use standard mechanical switches, he switches, or tmr switches if you'd like. TMR is also theoretically better than he, but the difference barely matters.

akko and monsgeek are sister companies, monsgeek fun60 ultra TMR is a great wireless gaming keyboard, one of the best if not the best one under $100, what's your budget?

first time hearing that, Keychron on other hand some have rly bad keycaps that break for 90 get fun60 ultra tmr if priority is gaming all around inky75 and weikav d75, don't get logitech, their more expensive ones are actually worse than cheap k835 and g413 se but those are not worth it either unless you get a rly good deal on k835, one of my friends was buying k835 tkls for like $25 a year or two ago

wootings except the 80 are pretty bad actually for a HE keyboard when it comes to performance, they are slower than average wireless HE board that costs under 100, it's all marketing, the best stuff are $200 but you can get a good 60 or 65% for under 100, I can recommend Monsgeek Fun60 Ultra TMR for 80-90 depending if you want wired or wireless

not really , I also have the Monsgeek Fun60 Ultra TMR (link below) and even tho TMR theoritically is better (literally went through multiple research publications for this) in practicality induction seems to be much better. Not only the inductive switches have more cosistent deadzones but also they sound way superior than HE switch which is my main point of the post.

[Monsgeek Fun60](https://preview.redd.it/9uf7fo90zzge1.jpg?width=1000&format=pjpg&auto=webp&s=6cdd1e016b38c41be25811acb9a4fc757ab41ba5) **For the past 5 weeks, I've been using this FUN60 Ultra TMR version from Monsgeek. My extensive thoughts below.** # TMR Technology — what is it? TMR (Tunneling Magnetoresistance) has been widely used in gaming controllers for quite some time and is now making its way into gaming keyboards. It is designed to [deliver even more precise accuracy than what the Hall Effect can achieve.](https://www.tomsguide.com/gaming/gaming-peripherals/so-long-hall-effect-im-only-using-controllers-with-tmr-sensors-from-now-on) [I took it from Monsgeek site](https://preview.redd.it/g012x64gzzge1.jpg?width=720&format=pjpg&auto=webp&s=9281ed6192c7de416ffa3f24c70cd11b1063ad39) Hall Effect vs TMR, here is the full article: [https://www.monsgeek.com/blog/tmr-vs-hall-effect-applications-in-magnetic-switch-keyboards-explained/](https://www.monsgeek.com/blog/tmr-vs-hall-effect-applications-in-magnetic-switch-keyboards-explained/) In short, TMR is here: 1. to boost the precision and sensitivity, 2. to ensure enhanced reliability for wireless gaming. 3. to implement both magnetic and mechanical switches in one keyboard, HE sensors can’t do that properly Overall, TMR offers more potential for advancing the gaming. And because it is more stable under varying conditions, it is considered to be ideal for competitive gaming in wireless conditions. It would be super cool to achieve the equivalent level of latency in wireless as in wired connection. In 3rd party [precision tests of FUN60 series](https://www.monsgeek.com/blog/is-0-01mm-precision-a-scam-for-magnetic-switches-keyboard/), it does show that the Ultra TMR version is relatively more precise than other hall effect versions. And it is thus more expensive as well — TMR sensors are able to accommodate both magnetic and mechanical switches as I’ve said. Hence TMR version is the ONLY one that offers the option to fit both mechanical and magnetic switches because TMR sensors are very sensitive so it can detect and interact with magnetic switches even if it is not placed at the center of the magnet. For HE sensors, they need to be placed at the center of the magnet otherwise they’re not sensitive enough to get triggered. Therefore, this causes interference with mechanical switches. MR does NOT decrease latency though, it’s about other things that are mentioned above. # In the Box [Box contents](https://preview.redd.it/4lf3kj7qzzge1.jpg?width=720&format=pjpg&auto=webp&s=2ba5f223bc0295e88be5afba285a7f0d75fea32a) * Monsgeek FUN60Ultra tri-mode TMR version * USB-A to USB-C cable * keycap puller * switch puller * dust cover * manual * wireless dongle The switches I tested with this one were Akko's Green Fog ones. # Spec and Features [Specs](https://preview.redd.it/t1tkw1u000he1.jpg?width=720&format=pjpg&auto=webp&s=de87ffd5260255ce76b4d32168ed3dd63cdd4aba) *Bottom line? This Fun60 Ultra TMR features some top-tier specs.* # Design and Build Quality [Front](https://preview.redd.it/5fhb4vj600he1.jpg?width=720&format=pjpg&auto=webp&s=5c3574abd444b9258fc6b7cd8299fefa06ed5f07) The Fun60 Ultra TMR stands out in terms of build quality, offering a pretty premium experience at this price. Its sturdy CNC aluminum chassis, reinforced by a durable steel base plate, offers a robust and premium feel, giving it a substantial weight and a better overall finishing. This contributes to a sleek, polished feel that speaks to its high-end craftsmanship. It really reminds me of Wooting 60HE, but it’s actually… better quality because Wooting 60HE is plastic-made at premium price. Fun60 Ultra TMR even features a place for a strap, just like Wooting. The typing angle is also very similar. The difference is in the switch for the tri-mode — it’s concealed underneath the CAPSLOCK key and you need to remove it every time you want to manually change the mode — of course, you can also do it via shortcuts but some operations require this switch to be pressed. The Fun60 Ultra TMR also features 4 non-removable silicon feet underneath the keyboard, non-adjustable. These elements combine to create a high-quality, refined product that sets it apart from most of the many competitors in the market, especially at this price range.

Good aluminum build adds to almost premium feeling, the design is very similar to Wooting 60HE.* # Keycaps These PBT-shine through keycaps look pretty solid and they really remind me of those used also in Wooting 60HE. They share similar characteristics, it’s clear that Monsgeek took it after Wooting. [Double-shot PBT shine-through keycap](https://preview.redd.it/b7ltgz6610he1.jpg?width=720&format=pjpg&auto=webp&s=3ae1be9e2f95b16c47b19f3aec492c7b041c2533) They also shine when used with the north-facing RGB of this keyboard, which is one really good of a feature here. It’s supposed to be ARGB (addressable RGB) with individually controlled LEDs for smooth, flicker-free lighting. With Alpha channel integration and a 500Hz refresh rate, according to Monsgeek — I haven’t checked that because RGB is the last thing a gamer should worry about but it indeed looks nice. To lower the latency though, you should turn the RGB off. One thing about the keycaps, after a month they have developed a certain shine and became more slippery on most used ones, take a look: [The shine on WASD after a month](https://preview.redd.it/44pmpr3c10he1.jpg?width=720&format=pjpg&auto=webp&s=6580d977272c9dc6ca7d8ed4455b793f1be8dfbd) *Bottom line? Good keycaps, they develop a shine and lose some grip after some time.* # Switches Monsgeek is a sister company of Akko and they manufufactures their own switches for this keyboard: Akko Glares. They come with extra pins for stabilizing, reversed polarity, and closed bottom for a better sound profile. Some specs below: * Total Travel: 3.4mm * Initial Operating Force: 25gf Min * Actuation force at 2.0mm Travel: 40±5gf * End Force: 48gf Max * Initial Magnetic Flux: 95+15GS (PcB1.6mm) * Bottom Magnetic Flux:589+50GS (PcB1.6mm) * Top/Stem/Bottom: PC/POM/PC * LED Diffuser They are also a bit similar in feeling to Lekkers used in Wooting, with much less stem wobble. The slight wobble is still there, as in every magnetic switch I’ve tested, but it’s nothing to be worry about. I personally don’t like too light switches, so I instantly found them very appealing. Obviously, they are factory lubed. One of the most important aspects of Fun60 Ultra TMR (and only this version!) is the platform cross-compatibility. Gamers now can mix and match magnetic switches and any 5-pin mechanical switches freely, something I’m not sure I’ve seen before. Imagine having only WASD keys swapped for magnetic switches, and leave the rest for mechanical for a classic mechanical typing experiences. That’s what I did for testing purposes. [Akko Green Fog mechanical switches](https://preview.redd.it/8xq7ja6q10he1.jpg?width=720&format=pjpg&auto=webp&s=f9020cad24eef477769577fb82c3125338b4ad6d) The ones I used were Akko’s Green Fog mechanical switches. With a 60g actuation force on top of enhanced RGB effects with the use of an LED diffuser, they felt really… heavy. Actually, the heaviest switches I’ve ever used. It took me some time to get used to typing on those, but I liked the feeling. These switches feature a POK stem, PC top cover, and PA66 bottom housing, offering a heavier typing experience with a deep and heavy thock sound. Their 5-pin design fits keycaps with standard MX structure. Some specs: * Type: Linear * Operating Force: 60gf ± 10gf * Bottom-out Force: 70gf max * Total Travel: 3.6 ± 0.4mm * Pre-Travel: 2.0 ± 0.4mm * Top Cover: PC * Bottom Housing: PA66 *Bottom line? Fun60 Ultra TMR offers great MagMech compatibility.* # Typing Experience and Sound Test Overall, I really liked the typing experience with both magnetic and mechanical switches. They keyboard was factory preluded, even with its tray-mounted design it sounds pretty good. The stabs are lubed well too, the typing angle on this non-adjustable keyboard was not bothering me at all. However, after 1 month, the most used WASD keys lost some of its initial quality, but it’s something we can live with. [Here’s the initial sound test out of the box](https://x.com/KapitanKloze/status/1884216539014205927) *Bottom line? Good sound out of the box, especially at this price point. The typing angle is acceptable even though the keyboard has non-adjustable feet.* # Software [My settings on FUN60 Ultra TMR, with 0.25 Dead Zone and 25% RT Stabilizer](https://preview.redd.it/22w0bcb220he1.jpg?width=720&format=pjpg&auto=webp&s=ed4e355d1190529f6d2e6b332e2b4780635685e0) So, here comes the most sensitive part of review for every magnetic keyboard. When it comes to HE keyboards, software is the most important thing. Fortunately, it is something you can constantly improve, unlike the hardware. However, I have to say that there have been some serious hiccups when I was thoroughly testing the Fun60 (4 weeks) but there are also some really good things there. Let’s start with negatives. * even though it’s a web-based software, you still need to download an .exe file to make it work. The whole point of web-based soft is that you can use it anywhere, without downloading anything. Here, it is the opposite — you need to install some file to kick it off. Weird. And it works only on chromium based browsers. * the profiles don’t work well at this moment: you can only rename it, share it or delete it, you can’t download it to save it for later. And every time there’s an update of the firmware, you lose your settings. So, that’s really a bummer. * mode switching is not automatic: when you connect the keyboard via the dongle for 2.4 GHz wireless connection, you still need to use some key shortcuts to pair it. And when you pull the dongle out, the keyboard still needs to be switched to the wired mode manually via shortcuts. Why is it like that? It should work automatically, for example, Chilkey ND75 did it in the right way. * when you download a profile from the Share Section of the software, you can’t store it and use later either, it automatically overwrites your main profile which is unacceptable. * Layers settings have also some weird issues, I had problems with setting the arrow keys that are non-existent on a 60% keyboard * Chord splitting (how quickly the keyboard reports multiple keys pressed at the same time) can be sometimes problematic, not a huge issue but it must be mentioned * some solutions are also unintuitive (Mod Tap, Layers etc.), some translations need to be fixed as well I am writing this article at the end of January 2025, so perhaps those bugs have been fixed at the time you’re reading this because Monsgeek work on updating the firmware and software all the time: in one month of testing, I had received 2 firmware updates that fixed some of the issues not mentioned here.But there are also good things and you need to know them as well. * Dynamic Roar Mode — something similar to Tachyon mode used by Wooting. It’s an algorithm that prioritized last 8 keys you pressed, giving them a boost to 16k scanning rate at the expense of the rest of the keys being downgraded to 4k scanning. While it’s true that other keys will experience a relatively slower scan rate, this adjustment is designed to be imperceptible during regular typing, even in scenarios where more than 8 keys are used frequently. In competitive gaming, however, most scenarios require repetitive use of up to 6 keys. This is where the Dynamic Roar Mode truly shines, ensuring faster response times and improved control. This feature was made possible by implementing the new and powerful ARM chip. * Dynamic Calibration, by some called AI calibration. Works really well * Dead Zone settings: they get rid of this empty feeling when you use magnetic switches right to the bottom. As far as I know, no magnetic switches are shorn of this. I suggest 0.25–0.3 mm Dead Zone * Rapid Trigger Stabilization: gives you great stability and gets rid of those natural human mistakes. I use 25% but don’t go too high because it adds latency, 0% is still fine. * SOCD works very well, even though you can’t choose priority of the keys yet * FUN60 Ultra TMR features a lot of magnetic and mechanical (5 pins) switches * Fun60 Ultra TMR has a real potential because theoretically MonsGeek/Akko team has the technical capability to further enhance the dynamic scan rate (e.g., 32K, 48K, or higher) for a few selected keys. However, implementing such changes would significantly increase power consumption in wireless mode. Further sacrifice would involve other keys being noticeable delayed during typing. * you can’t change the polling rate at this moment but at least it’s very stable at true 8k in both wired and wireless mode I’d love to see more improvements and more polishing to the software and firmware department. It’s very important and actually the only thing that keeps me from screaming “this keeb is a complete banger!” *Bottom line? Fix the software/firmware and it’s a banger of a keyboard.* # Latency and Gaming Performance The Fun60 Ultra TMR truly impressed me with its latency and gaming performance. When I tested it, the single keypress detection was around remarkable 0.6ms in wired mode and an equally impressive 1.1ms in wireless mode, showcasing how well the TMR sensors perform even when untethered, which also contributes to an extended battery life (all test performed with the most sensitive Actuation Point settings at 0.1mm and Rapid Trigger most sensitive settings on as well).Although the overall latency was slightly higher than some top competitors like Wooting, Nuphy, Iqunix, or Melgeek by a few ms\*, this difference is not noticeable in real-world scenarios. In gameplay, the Fun60 Ultra TMR felt incredibly responsive; I was pulling off complex maneuvers in trick maps with ease, feeling an immediate connection with every jump and hop. The keyboard’s tactile feedback, thanks to its high-quality switches, combined with software that, despite serious bugs, generally functioned well, made it one of the best keyboards I’ve gamed on. The stability of the switch stems was also a highlight, adding to the overall satisfaction. However, it’s not without flaws; I experienced one disconnection over a month of testing, which I attribute to software issues. For most of my gaming sessions, I used magnetic switches on the WASD keys for that extra edge, relegating mechanical switches to the rest of the board but I’d recommend sticking to magnetic switches all the way, even with everyday work. *\*I’m referring to the whole latency of the keyboard, not one single key press.* It’s time to say it — Fun60 Ultra TMR is the first wireless magnetic keyboard that does it right — very low latency combined with good battery life makes it actually the one to recommend for those who value portability and hate wires. *Bottom line? Very low latency in wired mode, only 0.5ms slower in wireless, among the industry’s top at this moment.* # Closing Thoughts In closing, I must say that my experience with the Monsgeek Fun60 TMR Tri-mode magnetic keyboard has been really positive. I’ve found immense satisfaction in its performance, both in the aesthetic appeal and functional aspects. The north-facing RGB lighting is nothing short of spectacular, especially at night; it adds a vibrant, dynamic glow that truly enhances my workspace. The tactile feedback from the keyboard, whether I’m gaming or handling everyday productivity tasks, is exceptional. It’s comfortable, responsive, and feels just right under the fingers. The build quality is commendable, especially considering the price point. It’s evident that a lot of thought has gone into ensuring this keyboard is durable and well-constructed. On the performance front, the latency of the Fun60 TMR is quite impressive, topping that of the Wooting 60HE, with just an additional 0.5ms in wireless mode. This level of performance is remarkable for a keyboard at this price, making it a true competitor in the market. The integration of TMR (Tunnel Magnetoresistance) technology has been something new and it’s a good thing. Not only has it significantly extended the battery life, allowing for longer usage between charges, but it has also enhanced the feel and stability of the magnetic switches. This blend of magnetic and mechanical switch technology offers a versatility that is rare in this price range, effectively bridging two worlds to cater to varied preferences. However, no product is without its flaws, and the software remains a serious letdown (I’m reviewing it at the end of January 2025). While it’s a pity that the software isn’t as polished as the hardware, it’s reassuring to see Monsgeek actively working on improvements. Over the 4 weeks of testing, I’ve received two firmware updates, which have begun to address some of the initial software issues. In conclusion, despite its minor software shortcomings, the Monsgeek Fun60 TMR stands out as a very solid contender in the budget keyboard market. It’s one of my favorite keyboards to date, offering a compelling mix of style, performance, and innovation at a price that’s hard to beat. I also personally… like it very much, not sure why to be honest. But it seriously clicked with me. If you’re in the market for a new keyboard that doesn’t break the bank but still delivers on quality and features and it introduces the TMR tech, the Fun60 TMR should definitely be on your radar. # Bullet Points * the very first TMR keyboard that combines the world of mechanical and magnetic keyboards * very good wireless connectivity with only 0.5ms delay compared to wired mode * latency is so low that it’s among top industry brands * true 8k polling and scanning rate, both wired and wireless * Dynamic Roar Mode that boost up last 8 key presses in terms of latency * very nice RGB, north facing * very solid build quality, almost premium feeling * software needs a lot of work, bugs polishing and overall refinement though * tri-mode connectivity switch is a bit of a clunky solution * switches (both types) and keycaps offer very pleasant typing experience * very good battery life * pretty affordable offer for what it offers * many FUN60 variants to choose from This will definitely stay on my desk for longer.

What about Montech Fun60 pro? I have it and it's working great for typing.

Fun60 Ultra is a good option… the guy your asking doesn’t even own a HE keyboard

Why not fun60 tmr it's just the same as Hall effect but better

Doesn't matter you still recommended it

A lot of he options are good but the software is almost always god awful. If the point is to just avoid wooting then like others have recommended keychron is a good shout, lemokey is also keychron just with slight differences in feature. Two personal picks I've tried are titan60, I got the pcb in china for about 30 euros but it basically has all the he features(software is usable but not fantastic), customize with your own case, keycap, switch. And Monsgeek fun60 ultra tmr, comes with a decent aluminum casing, supports wireless mechanical and he switches so you can have he switches on just the gaming keys, the default akko switches are he but super wobbly and cheap, but the board can be quite good if you swap on your own switches

I tested the keyboard, and when I check its polling rate, even with the RGB on, it rarely goes above 120Hz — whether wired or wireless.

Go for g502 for mouse or viper v3 pro if you prefer regular form factor. For keyboard I would recommend monsgeek fun60 tmr (but it's kinda expensive tho)

Check out the monsgeek fun60 ultra, it's basically a wooting 60he. Hall effect, 8000hz polling rate, can use magnetic or mechanical switches, aluminum alloy case so it's extremely sturdy and durable, and it's only about $80 with tax.

**·** The trigger and release points of general mechanical keyboards are fixed, but HE/TMR keyboard's are customizable. And currently many brands of keyboards already support 0.01 accuracy. That is to say, pressing 0.01mm further from the trigger point will input and releasing 0.01mm will stop. Relatively dynamic trigger and release points are more helpful in FPS games that require faster reactions. **·** Functionally, they're all pretty much the same. Power-wise, the TMR keyboard consumes less power. But for now, Hall keyboards have more options. So I would suggest that you can think in terms of preferred design or focus on features. Quality-price ratio: Fun60 Ultra/WIN 60HE Silent Switch:Elecom/DrunkDeer/Gamakay Low Profile:Air60HE/Made68AIR Softare: Wooting Design: A75 Master/Black Diamond 75 RT/ER75

fun60 on rtings tests is 0.5ms on single key, wooting 0.4ms fun60 0.7ms on multikey, wooting 0.5ms fun60 6ms 4k 12ms 8k chordsplit. wooting is 4.4ms on 4k and 9.9ms on 8k. [https://www.rtings.com/keyboard/reviews/monsgeek/fun60-ultra](https://www.rtings.com/keyboard/reviews/monsgeek/fun60-ultra) venom matches latency on single key with wooting but chordsplits: venom 4.3ms on 4k and monstrous 17.5ms on 8k(this is nearly double of wooting). [https://www.rtings.com/keyboard/reviews/geonworks/venom-60-he](https://www.rtings.com/keyboard/reviews/geonworks/venom-60-he) venom and fun60 did have lower deadzones. but not lower latency. [https://www.rtings.com/keyboard/reviews/wooting/80he](https://www.rtings.com/keyboard/reviews/wooting/80he)

I think only Monsgeek released TMR keyboards at this point, the FUN60 Ultra is great if you like the 60% layout, super low latency. If you haven't yet used a [TMR/HE](https://www.hlplanet.com/tmr-vs-hall-effect-sensors/) keyboard and play lots of FPS games then you should notice a difference, but mostly if you will use features like RT/SnapTap. If you prefer bigger layout then Drunkdeer A75 Ultra is a nice option and there are also Nuphy keyboards with low profile magnetic switches.

Yeah, the Monsgeek FUN60 Ultra is also such a steal... That's got TMR sensors for under a hundred bucks... That's crazypants!

I am also brand new and I chose the fun60. My main reason is because it was the cheapest one I could find out of these Hall effect Ali express keyboards. As many people have said most of these keyboards are the same with very small differences so just get whichever one you like the most or is cheapest

what makes some keyboards better for GD than others is "Rapid Trigger" which is something only analog keyboards can do. So your answer for this is the analog version. However I'd really suggest against buying razer keyboards. They are bad, like really really bad. Especially the huntsman lineup. There's cheaper rapid trigger keyboards than wooting 80he, like drunkdeer a75 or keychron k2he. Even if those are too expensive then you have options like mchose ace60 and monsgeek fun60 which are very budget friendly but are in 60% size only.

I just got one of those and I love it.

I agree, I have fun 60 pro and it’s really nice, feels like a steal for what I paid, the max and ultra are even better

How is it not on par with wooting? The TMR sensors are more capable than HE and I am not aware of the performance for this board but the fun60 has just as good if not better performance than the wooting so did monsgeek screw the pooch or whats up?

To add on a EPOMAKER HE60 or HE80, or MONSGEEK FUN60 would be good keyboard options. I'd personally go with the 80% after living with a WOOTING HE60 (Orignal model) and missing out on some of those f-keys.

Monsgeek fun60. Its around 40$ in my country, it has all effect (or tml, i dont remember) switches, has snap tap (they named it socd) and also rapid trigger function. Best buy of my life.

No price limit? WLMouse Ying 60/75, Wooting HE 60/80, Iqunix EZ60/75 Mid range? ATK RS7, VENOM60HE (PCB ONLY)0 Cheap? FUN60 HE, ATTACK SHARK 60HE. AJAZZ AK680 HE really depends on what you want out of the keyboard. In performance they are all similar, but with more premium options you get better software, less latency, and (most important for me) a more satisfying typing/gaming experience.

The Fun60 from Monsgeek is another good one and very very cheap. Unfortunately the software is not very good.

Yes, unfortunately compared to Wooting it’s pretty far behind. For regular keyboards VIA only matters to some users but for rapid trigger keyboards it’s super important, so the gap being big is a big deal.

I have the HE version (non-TMR) and it's really nice. Got some nice shine-through keycaps for it, really fun little keyboard. I main an Arbiter Polar75, and my alt is that little Monsgeek FUN60, two good options if you ask me.

True. Got a monsgeek 35$ HE keyboard and it switches are too light for me and the delay wasn't worth it (8-12ms). I preferred heavy switches and the heavy tactile switches to.
