Title: Love-hate relationship
Review: I have had a love-hate relationship with this mouse for years.The handling of the mouse is great, the double scroll wheel is very useful, and the programmable buttons are indispensable for me.However, since version 2.0 (today's version is 4.0), this mouse's buttons keep failing after a few months of use. It starts when double clicks don't get registered accurately, and then regular clicks fail as well.I'm on my 7th (!!!) mouse now, all free replacements from Microsoft. But it sure is annoying, having to call the Microsoft Supplemental Parts center (1-800-360-7561) every couple of months.If you look for durability, forget this mouse. Some of them failed me in as little as 3 months, but at the latest after 1.5 years.P.S. Microsoft Supplemental Parts center told me today they will NOT replace bad replacements anymore. Buyer beware.
