Yesterday I bought a magic mouse 2 because I had a mighty mouse but the scroll was not functioning anymore...
the new mouse is great, but it is not working anymore on my mousepad... The best I found is the put a sheet of paper white on top of my mousepad. Actually it worked great! and it still feels nice.
Furthermore I repaired my mighty mouse by putting few drop of alcool 70°... amazing isn't it?
Cheers,
Sylvain
