The primary buttons are built with spring tensioning. Underneath the chassis sit a power switch and weight tuning options. On its top, the mouse has 11 programmable buttons, plus an additional switch for toggling the scroll-wheel’s motion type-smooth, or precise with detents. On the outside of the mouse, you’ll find a suite of familiar features. The Hero 16K is reportedly more power efficient than its predecessor and can track at up to 16,000 DPI at 400 inches per second without introducing any motion smoothing. The Hero (High Efficiency Rated Optical) 16K sensor is the follow-up to the PWM3366 sensor seen in the first two iterations of the G502. It’s also why each Lightspeed device requires a dedicated receiver. Lightspeed is Logitech’s wireless transmission technology, which it says gives the G502 and other Lightspeed mice lower latency than other wireless rodents on the market. The mouse features Logitech’s Lightspeed tech, Hero 16K sensor, Lightsync LED syncing, and support for Powerplay wireless charging mats.

If you cracked open the G502 Lightspeed and looked inside, you’d find a collection of all of Logitech’s recent innovations in one place. Let’s dig in and look at what’s inside the mouse, talk a little bit about how Logitech put this thing together, and then discuss whether it’s worth the $149.99 asking price. We’ve been waiting a while, but Logitech has finally answered the call and brought us a wireless take on the G502 that’s worth crowing about. It turns out that taking a well-liked mouse that lots of people have strong opinions about and making it wireless isn’t as simple as removing the cord and jamming a receiver into a USB port. While mice like the G900 and G403 have gotten the cord snip and received the Logitech Powerplay treatment, one might wonder where’s the G502 been. The G502 is one of Logitech’s best loved mice and, according to the company, the most popular gaming mouse on the market since its release in 2014.
