normal mouse. It has been serving me on my home PC for 3 years already - it was bought for fun in AUCHAN for 350. Made my money in full. BUT. She did not leave the desktop, and did not drop. Used for both gaming and everyday work. Only the backlight of the mouse, which does not turn off after turning off / sleeping the PC, infuriates. I cover with a towel at night. In general - for the money - a reliable weight. No double clicks, no freezes, not noisy, the wheel "does not make brains". In general - no more than 500- I advise.
