It is decent while it's working
by RaduNot the best, but not the worst when it's working properly. Perhaps a bit too light for my taste. Mine started to make creaking sounds after a few months. The problem is that after using it lightly (8h/week) for one year and a half, the mouse started to move the pointer erratically on the screen. I have tried resetting to factory settings, reinstall firmware, etc but nothing seems to help. I've also used compressed air to blow the sensor area hoping it might just be some small dust particle blocking the sensor. It didn't improve anything. I am very disappointed really, because I had £15 mice that have lasted a decade or longer (I still have a Mad Catz R.A.T 3 bought back in 2010 which is working like in day 1). I believe it's still under warranty so I might reach out to support at this point.
