I bought a couple of these to use with some community laptops in case people do not want to use the traditional touchpad.
The main unit is a little light weight but they have worked well so far and I think they will continue to work for what we need them for.
It works, but the red laser beam comes through the opening around the wheel, which bothers me a bit.
My other mouses don't have this problem.
Works great and my mouse tracks amazing on it.
Very inexpensive, and it shows.
The cable is quite thin, with very thin insulation, and normal use of the mouse wore through the insulation where it meets the plastic shell until finally the mouse stopped working.
Right shape, wimpy microswitches.
If you need a mouse in a hurry off a store shelf, this'll hold ya until you find a betetr mouse.
It is not even a year old and the top is pealing off, will not buy again.
