I was out yesterday and picked this up at the local chain store. Before doing so, I checked reviews online. Im glad I paid a little more for this instead of getting the other option (Targus), which had terrible reviews. This mouse had many great reviews on Best Buy. This mouse is small, no matter what size you are. Im not sure if the other reviewer received a different one in the mail. There appear to be two listings for this mouse (m187 black) on Amazon. The other Amazon listing has two negative reviews about the mouse dying within several months. Ill have to wait to see about that. It was super easy to set up plug and go. I can see why it could get lost, since it is so tiny. The wireless is great if you are lefthanded. The mouse is very sensitive or else I am too used to my old clunker mouse, which was sometimes nonresponsive. http://garyadair.com/1049790
