I have my own opinion about the laser mouse.
My opinion is, yes it can be used on the clear glass surface but too bad it can not be used on a ceramic floor surface.
I found the lazer mouse to be wobbly/shaky while pointing in general. It is specially when playing games, it makes it very difficult to aim / hold the pointer in place.
Don't know if it is in general or mine is a bit spoiled
Well, it improved a bit after I cleaned the glass over the laser.
I am grateful tho the initiator of this thread that reminded me to rethink about the laser mouse. Otherwise, I just kept it on the side and was not using it lately.
