This is a good mouse I epically like how you can unlock the scroll while that will let you scroll through pages as fast as you want also the back buttons are good and easy to use when going back and forth in between web pages. The only down side for this mouse is the battery life is real short maybe about a week at best then you need to charge it other then that it is a nice mouse. 

Question: Do you have good control of the acceleration?
Answer: good mouse
