This is interesting. Someone actually invented a “fix” for the Magic Mouse. The Magic Mouse does not have any usage issue except that it is very thin and users will feel uncomfortable to use it for a prolong period of time. The fixed, is actually a simple silicon with suction.
Personally, I find the fix very ugly and defeat the purpose of having a slim mouse. It may make you more comfortable but it just doesn’t look right.
However, if you insist that the multi-touch function on the Magic Mouse is a must, and you need something to solve the wrist issue (pain after prolong use), you can get the MM fix for US$10 if shipped in US or additional US$3 for International shipping.
