I have the most common issue with the mouse. It start to release while dragging/selecting or makes double click when it is supposted to make singles and etc, before that i had RX1000 with same weakness. So i bought M505 for one main reason it have this unifying receiver but can you imagine what was mu surprice when i found that there's no unifying mouses only on the market (even on the logitech site). With this rates (less than an year for the first symptoms) i will get average large box with receivers.

Contact Logitech for a replacement. I think Logitech is generally good about warranty replacement.
In my case, I bought a M505 in 2010 and the single-click/double-click problem became too unbearable after 4 months. Logitech sent me a replacement M505. Now, 15 months later, the replacement mouse is suffering the same problem. The problem is very annoying. I just contacted Logitech for warranty repair or replacement, so hopefully it will get resolved again.
I bought a M325 a couple months ago for another computer. So for no problems with the M325, but I am worried about mice quality.
