Today we're taking a look at the Monoprice Dark Matter Hyper-K ultralight gaming mouse, featuring a 16000 DPI PixArt PMW 3389 optical sensor, Omron switches, and of course RGB lighting. The 60g weight facilitates easier and quicker movement during heavy duty use.Monoprice Dark Matter Hyper-K Review
The Monoprice Dark Matter Hyper-K is an excellent choice for anyone looking for a good, affordable mouse at $39.99 USD, while providing features you won't always get in other mice that cost double that! The lightweight nature combined with a full-size frame and paracord cable make the Hyper-K extremely responsive and easy to move.
