What reviewers say

Reviewers praise its comfortable shape, very light weight and smooth, responsive sensor, with RTINGS measuring outstanding click and sensor latency. The common reservation is the high price for a modest step up from the DeathAdder V3 Pro; RTINGS also noted it suits only larger hands and creaks slightly under a hard squeeze.
