This pointer does work, as long as it is intact. It has a small on/off switch on the left side, storage for the USB receiver inside, and is a nice small fit for the hand. The buttons are nice and "crunchy". However, it cannot take even one impact with the typical classroom tile floor. It flies apart, and the toggle for the switch has to be refitted just right into the top and bottom of the case, or it will not click back into place so that it is functional. This happened with the first one I purchased, and I exchanged it for another. The same thing happened to the second one. In both cases, I had dropped the thing only one time. I would not buy it again.
