I ordered this mouse because the listing said it works on glass. I have a 8mm clear glass desk and it worked inconsistently, so much so that it wouldn't work for me and I had to return it. Otherwise, it was a nice mouse, very light weight, it moved across the surface smoothly, buttons and wheels felt right. My right hand rested easily on it. Wish it would have worked on my desk.
Update: I upped it one star because i decided to keep it and order a $6 mouse pad since I wasn't willing to pay the price for the next one up that claimed to work on glass. Nice mouse, just not for my glass desktop alone. This mouse seems like it has an ever so fine texture compared to the super shiny one I was using but that's fine. It's comfortable.
