Got the mouse today. On the first day, I realized that the mouse is gorgeous for its money, He attributed the software to the merits, because. I also have a laptop from asus and the software is the same. The first 30 minutes was unclear location of the side buttons. I lost 7 hours with backlight and the charge scale did not fall (25% divisions). Soon I will order additional kayla on the spare wheel. Great mouse for the price.
