I can assure you that there are people who’ll pay lots to get this. I’m one of them too. The best mouse I’ve ever used. Paying up to $300 for 1, it’s that functional. (Though I’m glad it’s probably around $160)

Ah I see. I loved the MMO 7. It has many buttons I use happily. The best is the joystick. So good.

I have one slightly faulty version I bought in 2012. (Couple of buttons spoilt) That’s why now I’m waiting for the MMO 7+ to be released, the actual mouse is no longer in production

Yes. MMO7 is the best mouse I have ever used. So this looks great already with most of the design/functions similar and an upgrade to the software with certain hardware durability enhancements.

Yes and it’s the same one too, with just some improvements. Keeping the core there

I am looking to replace my old Naga wired mouse after several years, and I wondered how wireless versions of MMO mice do these days, and if anyone had any recommendations. I am not the hardcore FPS gamer, but I do play some hours of casual PUBG with my friends every week, as well as MMOs, so I really need the 12 buttons on the side type. Been out of the loop the last few years, so any feedback is appreciated. Tdlr; What's your recommendation for a 12 side button wireless mouse.

I had the old version, but as far I can see by a quick look it doesn't have the 12 button grid.

if you're looking for something comfortable for long sessions, maybe try ergonomic gear like MMO7 from Mad Catz. It's totally adjustable if it comes to size so it will fit your hand & grip for sure

please please please don't play on gear that doesn't fit your hand! Sooner or later it can cause pain or cramping. If you're looking for a mouse that can be adjusted to fit you, Mad Catz has some new options like the MMO 7 or RAT 8+ which I'm currently using for cs2. Both adjustable and customizable

YAAAAS! DWS 113g or MMO 7+140g. Both worth recommeding and both ergonomic

They're discontinued, but the Mad Catz M.M.O. 7 mouse is adjustable and gets pretty big at its largest. It also has a pinky rest that might give you some extra room to keep fingers off your mousepad area. They're on eBay for $100-200, so kinda pricey.

mmo 7+ will provide better more intuitive buttons. check out the 5 in one button, no more accidental presses.

Excited to see an update, somewhat disappointed that it looks like it doesn't include the interchangeable right side pieces. Hopefully an add-on accessory kit will be available?

TBD. I loved the original that I had years ago, it had some unique features that were surprisingly useful. * Horizontal scroll wheel isn't unique to this mouse, but this one got the location and feel just right * Thumb down (towards desk) button is the correct thumb button actuation direction imo, it just feels way more natural than trying to squeeze inwards to me - maybe just due to my big hands though. * The two inner left/right click buttons (8&9 on their layout) toggled left and right click to a 'hold' state. Click & release once for start drag, click and release again to stop drag, for example. Really handy to have as an onboard feature. * Best of all for me was the interchangeable right side plates. They have these on the R.A.T. 8+ (and others I think?). One option has a plate to rest your pinky on so that it doesn't drag on the desk, which is a total game changer if you have wide hands or long fingers. I would have bought one for home and one for work immediately, but without the interchangeable side plate I'm not 100% sold. I guess it'll depend on pricing.

There's really only 3-4 MMO mice on the market at this point. At least if you're looking at getting a "real" 12 button mmo mouse. Razer Naga, corsair Scimitar (and its wireless version), red dragon and steelseries aerox. And honestly, it all comes down to feel and fit since they're all solid mice - they all have pros and cons. Currently running a scimitar elite wireless - the adjustable keypad makes it fit most people. Previously used nagas, but expected lifespan of razer mice have gone a bit downhill over the years, naga is still solid though. Best MMO mouse ive ever used was the madcatz mmo7, which they're relaunching in a wireless version soon, but its a more untraditional button layout (which is why i liked it, as button placement felt more intuitive/had better flow than the rowed keypad), so it's not for everyone. If you dont want the full keypad, there's mice like the Rog Spatha.
