Those extra buttons along the side are also opportunities to customize for MMOs, to load up lots of spells. It was fast and responsive, and the DPI button near where my thumb rested let me take easy, precise aim at opponents. It has the basic form factor for a first-person shooter, and it worked great when I played Overwatch. With 11 programmable buttons, the G502 Lightspeed is equipped for any game. As with the original, there’s a button to switch between smooth and clicky, notched scrolling. It has a rubberized grips and feels really light. Some die-hards may notice that the scroll wheel, which was made entirely of metal on the original G502, is a little less beefy this time around. That means that if you use wireless charging, you can’t add the 8g of weight to the back. If you opt to use that, you need to replace the puck that comes with the mouse with a wireless charging puck. The G502 Lightspeed is also compatible with Logitech’s Powerplay wireless charging system (more on that later). The larger weights fit in a pop-out puck (more on this puck below), and a plate around the sensor reveals room for the smaller weights, which you can put in four different compartments.
If you prefer a heavier mouse or want to weigh the mouse more to one side or the other, you can add an additional 16g via two 4g weights and four 2g weights.
The weight system is on the bottom and highlights some of the biggest changes to the mouse.
