ROG Keris II Ace Wireless Gaming Mouse – Right-Handed Ergonomic, 54g, Tri-Mode Connectivity, 42K DPI, up to 107Hr Battery, PC/Mac Support - Black

I've been a Logitech mouse user for a long time, and through that time it's been primarily the G502 series. My lightspeed version had starting to act up on me a bit so I tried looking at different brands for a change. I spotted ths Asus Keris 2 in "Used - Like New" condition for $72.42 and decided to give it a try. The box the mouse came it was beat up and torn, but the mouse inside was flawless and still contained all of the accessories all wrapped up like new, well worth the discount from the new version. Pros * Lightweight - I never thought having a lightweight mouse would be any better, however since I've been using it I have converted. This mouse feels like I'm holding nothing in comparison to my old one and is a pleasure to use. * Materials - One of the downsides for logitech is they always use ABS plastic for their peripherals, any that have used any for a long period of time can note that the buttons get an ugly shine to them that make them look greasy, even after cleaning. The buttons for this mouse are made out of PBT so that should help, it also came with grip tapes for the sides and the buttons to help preserve the look for longer. The rest of the body of the mouse is made out of a nylon material that has a good feel and part of what makes it so stupid light while still feeling surprisingly solid. * No Holes - The weird trend with some lightweight mice is that there are holes in the body. True that it can make the mouse a bit lighter, but the holes can have a weird feeling when using the mouse as well as it lets more dust into the internals, making them impossible to keep clean. I appreciate the fact that Asus made this light as possible without these holes in the body. * Gaming/Wireless Performance - I've had no hiccups with the wireless nor have I had any issues while playing games. The sensor seems plenty accurate and I've had no issues with the buttons nor latency. I've been using the 2000 hz pulling rate since it's better on battery life while still helping a bit. The mouse feet that it came with feel smooth and of good quality, definitely better than the Logitech. * Useful RGB - RGB on a mouse for the most part seems pointless to me. You hand is covering it during use so all it really does is drain the battery faster. Asus seems to have seen that and only seem to use a single LED within the mouse wheel. This is nice because it can be used to also let you know once you need to charge and sips power compared to others, the battery life on this mouse is quite good. * Ergonomic - I know some people prefer symmetrical mice, especially us lefties, but nothing beats with the mouse has all the right curves which this one has. I have a medium size hand and this one fits it like a glove in my opinion, don't think I could think of any way to improve the way the shape feels. Cons * Slick Without Grips - I had to put the grips on mine because it would just slided from my fingers without. The coating is pretty slick to me so I'm glad that they included grips. The included grips may be a little cheesy looking but they have enough grip and texture without feeling "sticky". They filled in for this con, but I think it would be nice to include grips that match the mouse without the graphics. * No Hyper Scroll - This is the feature I miss most from my G502, the ability to click a button underneath and switch to an ultra smooth scroll which is great for large spreadsheets for work and nice for navigating other files/websites. Don't get me wrong, this mouse wheel feels great as the wheel is grippy and the scroll feel/click is excellent. I would just love a version of this mouse with hyperscroll! In the end I'm glad I decided to move away from Logitech, I've been very happy with the Keris II. Even though the mouse had cons for me, they made up for one by including the grip tape and the other was just functionality that I miss. Overall I would highly recommend this mouse to anybody that's looking!

One of the most comfortable mouse that I have used in a while, I like how lightweight it is and plus I feel I am better using this guy because of reduced strain on my hand and wrist. Battery life is pretty good too. Overall I recommend this mouse to anyone who is looking proper ergonomic gaming mouse.

Feels good in the hand and the software that accompanies it is also very customizable for casual to high performance situations.

Armoury crate is bad enough to deter anyone from wanting to get this mouse. The mouse I got is also defective and doesn't work when plugged in with a USB only.

The bottom of the mouse isn't perfectly flat, so when used on a glass mousepad it wobbles like a chair with a broken leg. Tried swapping the mouse feet with the included ones but it didn't fix the problem.
