It's an open secret in the mouse review community that Chinese brands offer a huge advantage in terms of value for money, often replicating the shapes, sensors and features of the best mainstream Western mice for half the price - or less. That's certainly the case with the subjects of this review, the $90 Mchose K7 V2 Ultra+ and $80 A7 V3 Ultra+, which closely resemble the $160 Razer Viper V4 Pro and the $180 Logitech G Pro X2 Superstrike respectively - two flagship-grade mice from the two largest Western mouse brands.
Within these matching symmetric shapes, Mchose has popped in the highest-end sensors, wireless transmitters and microswitches that it has access to, resulting in exceptionally capable mice that feel familiar - with prices that are pleasantly affordable compared to the OGs.
Let's quickly run through the specs. Both mice weigh less than 60g and use a PixArt 3955 optical sensor which is capable of native 1K, 2K or 4K sensor polling, while max wireless polling rates top out at 8K via wireless or wired connections. A modern Nordic nRF54L15 MCU has been used to ensure battery life stays reasonable, even at higher polling rates, and DPIs top out at 40,000 on the K7 and 50,000 on the A7 - way higher than you'd ever need. More critical is the choice of microswitches under the left and right buttons, and the Omron D2FC-F-7N is a great mechanical choice rated for 100M actuations. Finally, the scroll wheel uses the popular TTC Gold encoder. It's all very high-end stuff, and not at all what you'd expect from a Razer or Logitech mouse with an MSRP under $100.
However, part of what you pay top dollar for on a flagship Razer or Logitech mouse is special tech. In our Viper V4 Pro review, its extremely efficient design and resultant battery life was the key, for the X2 Superstrike I reviewed at IGN, it's all about the novel rapid trigger mouse click, which does away with the traditional mechanical mechanism entirely. The Mchose flagships are more limited in that respect, with neither exceptional battery life nor a unique clicking experience. However, they're also priced accordingly, so I think that's OK.
Another traditional benefit to going with a mainstream mouse brand is that you get a mature, powerful software solution that integrates with different games, gives you the ability to customise settings like button mappings, and allows access to an ecosystem - for example, activating Elgato functions with a Corsair mouse, or synchronising lighting with Razer Chroma.
That changed a few years ago, when these smaller boutique brands started using web-based software that was easier to author, required fewer dodgy downloads and didn't take up any RAM on your PC. Western brands are now jumping aboard the same ship, but now it's those early adopters that have the more mature offering - and Mchose has done well here. The M Hub is logically organised into key config, DPI, lighting, performance and "others" tabs; profiles can be stored onboard or in the cloud; updating firmware can also be achieved without separate downloads. There's still the option of a traditional app if you want it, but the web version is blissful by comparison. You don't get Razer's excellent library of game integrations, but it's no big deal to miss it.
In terms of actual performance, the K7 V2 Ultra+ and A7 V3 Ultra+ are solid. The inclusion of a dock makes battery-draining 8K play much more viable than mice you need to plug into a cable, and you can play for several days at that top setting without needing a recharge anyway. Battery life at 4K, 2K and 1K is significantly better, of course, and if you're not playing competitive games you'll probably want to stick it at 1K and forget about it.
Thanks to the familiar shape and high-end specs, I found it easy to take out rooms of enemies in 007 First Light - so much so that a lot of the intense "defend the thing" setpieces had extended periods of downtime - and the mouse felt extremely responsive in Counter-Strike 2 too. I don't think the performance, build quality, or design surpasses a mainstream flagship mouse, eg the lighter Razer Viper V4 Pro or fancy-clicking Logitech G Pro X2 Superstrike, but I don't think you're sacrificing too much here either.
Ultimately, if you want a high performance mouse but don't care much about the logo on the side, the Mchose K7 V2 Ultra+ and A7 V3 Ultra+ are excellent. You're getting 99 percent of the 2026 mainstream flagship mouse experience, paired with good web software, at around half the price. If you have liked Razer mice in the past, go for the $90 K7, otherwise, go for the safer (and slightly cheaper) $80 A7.
