Query: Logictech V150 Mouse

Received promptly, works fine. I've found the life of these (used with a laptop) is about 2 years. I buy only Logitech, as I think they are the best.Update on 4/26/12: Downgraded from 5 stars to 1 star. This mouse is a disappointment. It is jumpy, and I often have to double click two or three times before it will do the job. I've had several Logictech mice over the years, but this may be my last.
