Great mouse! Pros: You can use ready-made functions or add and bind your own script, all this is not too difficult. The little button next to LMB is very useful. The cursor does not break. Rough plastic - the skin does not sweat. Got cons: Changing the resolution is inconvenient, it takes too long to switch cyclically in a circle. There should only be two. Or I didn't understand something. Some people may not like the rough plastic.
