Negative Positive
Title: Not as Advertised
Review: I need a handheld optical trackball, so I bought this mouse as it is listed as a 'Wireless Optical Presenter Mouse'. But what it fails to state is that the trackball is totally mechanical - not optical. As if that were not bad enough, the trackball is so erratic and twitchy as to be totally useless.I gave this product one star only because I cannot go lower. Definately NOT recommended.
Is the review positive or negative?
