So, before that it was SENSEI rubberized, and everything was fine, until the wheel, when used, began to live its own life, you turn it in one direction - it turns anywhere, but not where it is needed. Soldering did not help, it was decided to ate the mouse, I bought TEN, and my joy knew no bounds . six months. That is how long the wheel lasted, and not very active use (I played on microsoft 1.1a when I was young, and there the wheel was used very often), only for rare surfing through the pages. Disappointed, will need to look for something else, because. every six months to change the mouse at the price of a monthly meal - no thanks.
