Over the past year, ASUS mice have come a long way. Every time I reviewed a new release from ASUS, I was pleased to see that something had been improved over the previous one. With the ASUS ROG Keris Wireless, this process comes to its culmination.

Much like all other recent ASUS mice, the Keris Wireless uses PixArt's PAW3335, which is known to be fairly difficult to implement. It seems as though ASUS has put their experience with this sensor to good use as the implementation on the Keris Wireless is near-flawless. CPI deviation is stunningly low, general tracking excellent, and aside from 125 Hz and 250 Hz in wireless mode, polling rate rock-solid across the board. The isolated wireless delay is around 1.5 ms, which is good but could be improved further had a wireless extender been included. Still, coupled with the very low click latency and above average battery life, overall performance of the Keris Wireless is top-tier.

When it comes to build and button quality, the Keris Wireless is also right up there with the best. The main buttons deliver a firm and snappy click response, and should the installed switches wear down, can be replaced easily owing to ASUS's push-socket design. Additionally, the main-button pieces are made out of PBT, which is more durable and less prone to getting shiny over time than regular ABS plastic. The scroll wheel provides highly tactile and controlled scrolling, and if so desired, the side-button pieces can be replaced with differently colored ones. The Keris Wireless is fairly light at 79 g, yet build quality is impeccable, with zero creaking, rattling, or flexing. The mouse feet have been improved as well, and a set of replacement feet is included. Same as previous ASUS wireless mice, the Keris Wireless is capable of 2.4 GHz, Bluetooth, or wired operation, but this time around, the much more flexible charging cable makes wired use actually worthwhile. Flexibility is almost on par with the charging cable of the Glorious Model O Wireless, which is no small feat. The Keris Wireless is also capable of fast-charging, which allows for a virtually seamless experience.

As well as the Keris Wireless performs on the hardware side of things, as poorly it does on the software front. Although ASUS has by now at least released a dedicated uninstalling tool to ease the process, the general experience with Armoury Crate can only be described as poor. Having to deal with the unreliable installer, the incessant need to install modules, and countless processes running in the background overshadows the fact that functionally there isn't much wrong with Armoury Crate once it's finally set up. Still, Armoury Crate is one of those software suites I just want to install, set everything up with, and then uninstall ASAP.

All in all, the Keris Wireless is nothing short of impressive, and when looking at the competition, quite fairly priced, too. The $129.99 DeathAdder V2 Pro, $159.99 ASUS ROG Chakram, $99.99 ROCCAT Kain 200, and $49.99 Dream Machines DM6 Holey Duo are all much bigger than the not even EC2-sized Keris Wireless, and in the case of the latter two, nowhere near as good. Outside of the Pwnage Ultra Custom, which I haven't tested, the ASUS ROG Keris Wireless simply doesn't have much competition as a medium-sized, right-handed ergonomic wireless mouse, and therefore certainly deserves our Editor's Choice award.
