This is a classic case of false advertisement/description

I really enjoyed the nice case it came with, nice and compact for carrying in suitcases later on for travels

It seems to track fine but the case is unusable as is.

This mouse totally delivered, other mouses were too small for my hand, other mouses didnt come with a charging chord, and other mouses didnt come with a nice traveling case (which is awesome if you are using it for a laptop like i am)
