Editor's Choice

The Asus ROG Keris II Ace has the specs pro gamers need from a wireless mouse: a high DPI ceiling and an 8,000Hz polling rate with not a gram of weight more than necessary.

5 top gaming mice to buy in 2024

With a 42,000-dpi optical sensor and a wireless polling rate of up to 4,000Hz, the Asus ROG Keris II Ace is right up there with its rivals (and also slightly cheaper at S$189). It's designed for right-handers, and is comfortable to use. Buttons are clicky and the scroll wheel is tactile. And you don't need to install any software to tweak settings like polling rate and DPI — they can be adjusted via onboard buttons.

Can Buy

At S$189, the Asus ROG Keris II Ace is cheaper than the similar lightweight gaming mice from Logitech and Razer that cost over S$200. These mice have similar features and performance, and are great for games that don't benefit from having more buttons.
