There are two side buttons where your thumb rests, two buttons up top, and a clickable scroll wheel. Something to note is that this mouse doesn't have many buttons. It has handy features like an on/off switch, internal USB receiver storage for when you're transporting it, and PowerPlay compatibility. The G Pro X Superlight has other gamer-centric features as well, like the accurate HERO sensor with tracking up to 25,600 DPI with zero smoothing, filtering, or acceleration and extra large PTFE feet. That's pretty amazing considering the fact that there's still an internal battery that's rated for 70 hours. This mouse is so light that it weighs about half of the Logitech G502 Hero wired mouse. That's 25% lighter than the first generation G Pro X and easily the lightest wireless mouse that Logitech carries. Thie Logitech G Pro X Superlight weighs in at under 63 grams. It's biggest claim to fame is its weight, or the lack thereof.
The Logitech Pro X Superlight is a high-end mouse that's specifically catered towards gamers.
