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

In my opinion, the ASUS ROG Keris II Ace Wireless Gaming Mouse is a game-changer! First of all, at just 54 grams, it feels amazingly light—which makes extended gaming sessions so much more comfortable. You hardly see it in your hand. The AimPoint Pro 42K optical sensor is just unbelievably remarkable. Since I began using this mouse, my FPS game objectives have certainly gotten better. A great benefit is that shots seem to be precise and quick. The optical micro switches also give a lovely clicky response that I especially like. It's fulfilling and gives every click pinpoint accuracy. The SpeedNova wireless technology stands out for me in particular. Wireless performance made me slightly skeptical, but this mouse is really quick and has no obvious lag. Additionally, it has a wonderful polling rate booster, therefore everything seems crisp. The elegant black style appeals to me as well; it looks really cool on my gaming setup without being too showy. Overall, the ASUS ROG Keris II Ace has provided a fantastic experience whether you are a competitive player or only someone who like to play for amusement. I am quite pleased I made the change.

I love this thing! I’d been using another mouse I purchased a few months ago and have hated it. Imprecise and the coating felt so slippery. This thing is the complete opposite. It’s super light, the top is fairly smooth but the sides have a coating that add a coarseness for good grip. The build quality feels really nice, great packaging with some little goodies included. It’s not RGB entirely but the scroll wheel does have one which is fairly subtle. Great purchase for when I’m playing non MMOs. Will keep this review updated as I continue to use it more!

This is a great mouse and I am honestly torn between the Keris II Ace and the Chakram X Origin mouse. The Chakram X Origin is much bigger and fits my hand perfectly, the Keris II Ace is a bit smaller, but far lighter than the Chakram X Origin. Both perform fantastically and both just glide on the mouse pad (The Keris II Ace more so than the Chakram X Origin!), but where the Keris II Ace beats the Chakram X Origin is being able to use the Keris II Ace in wireless mode with above 4000hz polling rate. The Chakram X Origin only goes up to 1000hz polling rate in wireless mode. If you're primarily using your mouse in wireless mode, definitely get the Keris II Ace, as it has up to 8000hz in both wired and wireless mode. The only real downside is that the polling booster is pretty chunky, and may overtake another USB port on your motherboard or laptop.

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!

Overall impressions were good. The unboxing experience really conveyed the premium aspect of this product. Once in my hand, it felt a bit too big in my medium-sized hand but, it is overall comfortable. The buttons are nice but I do miss having left and right buttons on the scroll wheel like other traditional mice. The scrolling speed also suffers from this and it can be pretty tedious when scrolling through websites. It really shines when you use it for its intended purpose: to play games. The mouse is light, responsive, and performative in FPS games. However, when switching game to game, I found the DPI button to be in a awkward spot (at the bottom of the mouse). That’s really my only gripe with the mouse. Other than that, the mouse excels in every other aspect you’d expect. It’s a great buy, especially with the current sale. 8.5/10

Lighter and nice curve, good gifting option

De verdad no imaginé que fuera tan pero tan ligeo y cómodo. El cable es extremadamente suave y se agradece. Su dongle es compatible con el teclado Azoth, de modo que solo con un dongle conecto teclado y mouse.

Great mouse, lightweight, good for gaming

It's a good mouse. Lightweight, fast, the grips are enough such that sweaty palms don't glide around, and the stock skates are already quite good. However, the mouse lacks a secondary middle mouse button (usually marketed as a dpi switch) which I usually use for for music play/pause. I think mice with that price should always have a third customizable button, as much cheaper mice will have at least 3 while being equally light.

Very light. Smaller than my death adder pro v2. Great mouse for small hands.

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.
