A good little mouse in a small form factor, this is what HP offers us here. It connects to your PC (or Mac, a priori, but I do not have a mac on hand) via bluetooth, no adapter (easy to lose) is required. Or provided elsewhere. Especially nice for an ultra portable, which typically has only one or two USB ports, which have to be done.
The mouse seems a reasonable quality (there is nothing to make a fuss, but it is acceptable) and runs on one AA battery (Energizer battery included).
The only two complaints I could do it are lack of rewind button, and the thickness of the corny (a bit too thin for my taste in hand). I leave it five stars because these two complaints are related to the form factor, and that is its most positive.
