Worst Experience. Just one word for them "LIAR". All they say is lie and they mislead you and the company badly. I was accused of damaging my own mouse to a limit that "cannot be repaired" and when i complained to Logitech then they said that i have repaired that "unrepairable" mouse "myself". How idiotic? Later got it replaced after talking to a higher official at logitech. Thank You Logitech!
