I would rank this mouse as one of the very best I've ever used. The design is quite user-friendly; formerly, it was a symmetrical mouse manufactured by Glorius; however, this one is significantly more practical. I have already taken care of the software that the raiser provided. It continued to be the most convenient option among all of its rivals despite their efforts. The mouse moves really smoothly, especially taking into account that it was tested on a carpeting that was of very poor quality. Has some pros Very gorgeous and comfortable. Excellent piece of software. The wheel was to my liking. Some cons: Use the button on the side to lower the sensitivity. I am aware that this is a characteristic of a particular model, and as a result, I do not remove the star; nonetheless, the fact that there is a button under the thumb does not make things any more comfortable for me. But in most cases, it is not essential. Unfortunately, in contrast to versions sold by competitors, the weight of this mouse cannot be adjusted. Perhaps it is significant to certain people. Of the obvious shortcomings, this is a small click of the wheel, if it is tilted to the right / left (the click is not pressing a button, but before that, some kind of stranger), but in principle it does not interfere with use, although this may be a marriage, but I am too lazy to return
