Title: sticking buttons after 6 months
Review: I replaced my Microsoft Optical Mouse with the MX 310 and initially felt very happy with my decision. The Logitech has a much more solid feel with more precise control. After 6 months the right mouse button started to stick and more recently the left button would intermittently require more force to click. It has become extremely annoying having to consciously push the mouse buttons each time, almost like having to push hard on a pen top to get it to unsheath.I wrote to Logitech with my problem and they said to bring it to a service center. I'm going to bring it back to Best Buy and see if they'll fix or replace it.
