Pros: Good buttons, nice feel in hand, good weight

Cons: I've had this mouse for two years. After a few months of owning it, it started this strange double-clicking issue. Sometimes you click, and it will double click instead. When you try to click and drag, it will someones release the click partly through. This is a known error with many Logitech mice, which Logitech has acknowledged. However, their solution does not work, and they will not recall. Like I said, I've had the mouse for 2 years. It goes through phases. Someones it will work perfectly for months at a time, and other times, it will be absolutely frustrating and double clicking on almost every click. Makes gaming very difficult if not impossible. I've hung on this long because I spent $65 on this mouse and didn't want to throw that investment away. However, I am stubborn that way. I will definitely not buy another Logitech mouse until they address this issue! Also, the charge only lasts about a day or day and a half now, meaning its essentially a corded mouse since I have to plug it in all the time. I guess that happens after 2 years though...
