Hello, This is an original HyperX mouse in excellent condition, fully programmable with their software. It offers complete control over all buttons (two side buttons plus DPI button). (It may occasionally get stuck at startup, which is common in most mice, but you can fix it by pressing the scroll button and DPI button together, and it will work fine without getting stuck.) (This happened to me twice and then disappeared.) It has special gliders installed for smoother movement. Selling because I bought a new mouse. The new one was around 159. This one is clean, asking 80.
