Earlier this year, I reviewed the HyperX Pulsefire Surge, a gaming mouse with really pretty RGB LED light effects. The subject of this review is the Pulsefire Haste, a model that hit the market in October 2020. Haste is an apt name for a mouse that focuses on ultra-light-weight and HyperX really shoots for the limits of what's technically possible by delivering an eSports mouse of this size at a weight of just 59g.
