Since switching to this mouse 2 weeks ago i am having wrist pain for the first time. I placed my original mouse next to it and the new one is alot higher which causes the wrist to be on a much more of an angle. So having figured that out reason for replacing my original was one of the black slide underneath came off and the only way to re-attach it was with crazy glue. Its holding but doesn't feel quite correct. After checking the Apple.ca store today they don't show the original mouse as be available for sale. Anyone know of a different route to obtain a new original mouse?
