Don't trash your old Logitech Mice...
My fixed G7 was exhibiting the erratic double-click again about two months after I originally fixed it, and I broke the copper spring on the second attempt to flatten it out. I was a bit dejected, until I remembered that I had an old MX700 collecting dust in one of my desk drawers. I figured that since the MX700's body design was similar to my G7, there was a good possibility that it used the same clicking mechanism. I popped it open and voila! Count 'em - FIVE exact-match copper springs available for future mouse repairs. I'm going to have my G7 forever.
