If you’re a #gamer, you know a good mouse is the difference between landing a combo and getting your butt kicked. Also, a sensitive mouse is important to getting the perfect cut if you work on music, audio, or video production. This wired mouse has eight buttons, meaning you don’t even have to touch your keyboard to take action. A PixArt 3325 sensor lets you adjust DPI up to 6,500 with saved settings for easy transitions. DPI up and down buttons let you cycle through your four favorite mouse sensitivities. A 1,000Hz polling rate communicates your mouse position to your PC every 1 millisecond, reducing lag from your hand movement to the on-screen mouse movement. It was tested to last 10 million clicks, meaning this sub-$50 investment will last you game after game.

Why Trust Popular Science

Popular Science started writing about technology more than 150 years ago. There was no such thing as “gadget writing” when we published our first issue in 1872, but if there was, our mission to demystify the world of innovation for everyday readers means we would have been all over it. Here in the present, PopSci is fully committed to helping readers navigate the increasingly intimidating array of devices on the market right now.

Our writers and editors have combined decades of experience covering and reviewing consumer electronics. We each have our own obsessive specialties—from high-end audio to video games to cameras and beyond—but when we’re reviewing devices outside of our immediate wheelhouses, we do our best to seek out trustworthy voices and opinions to help guide people to the very best recommendations. We know we don’t know everything, but we’re excited to live through the analysis paralysis that internet shopping can spur so readers don’t have to.
