I used the mouse for 5 years and 7 months, and changed the mouse, only because the left button began to double-click (but this is apparently from old age)! That's why I decided to take another mouse from this company - model: T70 Now let's see how long it lasts. 12/23/2022 - Bloody T70 turned out to be worse than V8! So I switched to Mad Catz R. A.T. 8+ and no regrets!
