keychron k3 or k7 might work good for your budget, they have bluetooth and pretty solid for gaming. i use k3 for work stuff and some casual games and battery lasts forever the dual connectivity is nice when you want to switch between devices quickly. works great with ipad too, just remember to check if you want low profile or regular keys before buying

I went all out earlier in the year and tried a bunch of low profile keyboards. Nuphy air75 he / Keychron K3 / Nuphy air75 v2 / Keychron B1 / Logitech MX mechanical / Logitech MX / If you want to buy a keyboard that will last you the next 5+ I would spend the $$ on the Nuphy HE or the Kechron K3, specially if you are going to use it for gaming. Otherwise the best cheap is the Keychron B1. I kept the Nuphy He, because I loved the magnetic keys, and the Keychron B1 because I can take it anywhere. My advice is that if you are going to be moving around with any of these, you must buy a keyboard case. Non of them felt like they would withstand a drop. Note: I did not try the lofee because it was the only one that required me to pay shipping fees if I returned it, so I didn’t take my chance. But I have seen great reviews.

If you're fond of low profile keyboards, I couldn't recommend Keychron K3 Max enough. Good build, don't need software as you can configure it via browser, supports VIA/QMK. My only gripe is that keycaps are not shine through, but you can easily replace them if that bothers you. Be careful when you shop, as there are many variants such as rgb/white, 8K/1K, hotswap/non-hotswap, etc. Also make sure you buy from your local retailer of Amazon, as Keychron's customer support is abysmal if you buy directly (check Keychron's subreddit). I would generally avoid those tacky "gamer" boards as they are overpriced. If you have a low budget, go for redragon k616 fizz. I had k617, The only difference is that the k616 is wireless.

It’s not the full key set you want, but I put together a Keychron K3 with YMDK DSA profile keycaps https://imgur.com/gallery/writerdeck-ipad-air-on-nulaxy-foldable-metal-stand-keychron-k3-with-ymdk-dsa-profile-keycaps-TtwxNcI#koN4qNF

Ok so IQUNiX low profile (MQ80 and Magi series) are the holy grail now when it comes to pure feeling. Also Nuphy Air V3 series - same case. As for Keychron - the HE and Ultra low profile series are on Kickstarter BUT we do not know anything in real life. Also I don't know about any issues with K max series - rocking K3 Max for half of the year now without any issues. The only problems are: feeling (is really "meh" in comparison with market leaders) and the battery life with light turned on it... let's just say not so good... Despite that it's rock solid keyboard, I'm using it for coding, writing (I write a lot) and occasionally gaming.

I am not comparing the switches - please stop. I understand the difference and what's more important: I am comparing keyboards themself - their foams, padding, case, damping - and overall feeling. They are similar yet You cas feel the difference. The V3 is just better (even if the switches would be the same). To be fair Wisterias and Cowberrys were more than good enough tho and I wouldn't mind if they were used in v3. Also I do not care about QMK - mainly because I usually don't use it even on boards that has this functionality. No offence but I do not care if You had any problems with blutooth, pal. Many people had - even on this subreddit and it's common issue with v2 (and one of reasons why people were switching to Keychron back in the day) - even on Mac systems.

Interesting that this whole discussion about nothing started with no QMK support (which again I would say is not that needed at all). I was telling about my perspective and feeling. You are trying to PUSH your point of view here (which is not nice to be fair) which I simply cannot agree with (because switches are not that important FOR ME anymore if they are at acceptable quality point which is not that high nowadays) and FOR ME the rest of the keyboard - caps, padding, casing, foams, gasket are far more important than switches themself (tested on many boards with many switches - been there done that). That's why I pointed it out and that's why I THINK V3 is far better than V2. It could not be the same for you and it's fin,e but again: do not try to force Your perspective here - it's definitely not nice and again: please stop it. As for bluetooth: I was a tech support for big company for few years - the bluetooth sucks on both Mac and Windows respectively but what I can say: if device works fine with it (bluetooth connection) - works on both ecosystems, despite card providers (Broadcom, Intel, Mediatek, older Killer, etc.). Some people I know experienced huge amount of problems with bluetooth on Air v2 (both on Mac and PC - which was backed on few reddit threads with same issues) and switched to Keychron (they were easily available in my country and there were not so many alternatives when it comes to low profile back then). I feel like it's somehow personal for You, pal...

k3 max is way better for 75% low profile, 2.4ghz, cable and bluetooth

some recommendations: * Keychron K3 Pro/Max (Max support 2.4GHz wireless, Pro does not. Both support Bluetooth) * Lofree Flow/Flow Lite (Flow has an aluminium case, supports QMK/VIA. Flow Lite has a plastic case and no QMK/VIA. Both are wireless via 2.4GHz or Bluetooth. * Nuphy Air75 V3 (would prefer the 2 aforementioned boards over this as Nuphy has had issues with exploding batteries with older keyboards, but so far there has been no reports of this on the V3. Supports 2.4GHz wireless and Bluetooth. The Blush Nano switch is basically the Red switch but a bit more mushy, similar-ish to your K380 in terms of feel.) Tips for keeping the battery healthy. * do NOT use the keyboard in wired mode, unless you specifically remove the battery from the keyboard. * use the battery until it is around 20% left, then charge it to around 80%. just try charging it and testing how long it needs to be charged for to reach that level for your first time and take note for future reference. for the Logitech MX Mechanical/Mechanical Mini, I wouldn't get it as it does not support any sort of customizability in the form of QMK/VIA or alternatives. it's USB-C port also does not support data transfer, only charging. so you can't use the keyboard in wired mode, which will inevitably happen when the battery swells and you are forced to remove it and use the keyboard in wired mode.
