The mouse is worth its money. Even despite the raw software, everything is clear, the sensor is good (but not gaming). Someone will not like the scroll wheel (but I got used to it in 1 day) Pros below: The charge lasts really long. I charge once a month (provided that I use every day for 6-8 hours) Cons below: The software is raw. In some programs, the side wheel does not work. At first I thought it was a defective mouse, and then I switched programs and realized that it was only a matter of software. (treated just alt+tab)
