Our Verdict
While not designed specifically for this use, the ASUS ROG Keris II Ace is decent for work. Its comfortable right-handed shape suits a variety of hand sizes and grip types, and its build quality is excellent. It also supports multi-device pairing with up to four devices using Bluetooth and its USB receiver. That said, its scroll wheel lacks a free scrolling mode and L/R inputs, and some functions don't work natively on a Mac without first configuring the mouse on a Windows machine.
