that's not a button. I have one now. It does not move.

picrel is currently my favorite mouse. I am on my second one already though. The current one has lasted me almost 2 years but mmb has started double clicking and the rubbery side grips have started to wear down.
That said, I only use it wired because it dies within a day or two at most. Don't bother buying the extra charging station, it works fine but it's just another retarded accessory when you're going to be leaving your wire close anway.
