This is my first device from the Corsair brand. I was very pleased with this rodent. Everything is relative. Only now I realized that the mice that I had before were not what I needed. Unlike other brands, HARPOON has a very comfortable shape. Due to its light weight, it is comfortable and easy to manage. Strict design, bright illumination add attractiveness to the device. The mouse wants to be used again and again. The wheel spins almost silently. Equipped with rubber coating. The click on the wheel is quite quiet without a strong dip. The plastic itself with the main buttons under which the microphones are hidden is a bit rough. At first it confused me a little, but now it seems that I'm used to it and without it, the grip and grip are no longer so tactile. Plus, I think over time it will become smoother with wear. The rubber pads on the sides were not worn or dirty during this time. The mouse feels completely like a single monolithic object. No backlash and squeaks. The main buttons have a sharp and clear response. In my opinion, a little noisier than my counterparts, but I do not care. Cable without braid, quickly enough "straightened up after purchase." Playing on a cloth pad, there were no problems with the sensor either. Everything is fine. The iCUE program has become a real discovery for me. It seems like this program can do everything. No lags or bugs were found, as others write.
