Has long been looking for a small wireless mouse for my laptop, I also often go to have it. Therefore both mouse and the USB plug should be small and easy to handle and thereby are priced in the lower range. Now I found this mouse with a renowned art dealer a few days ago and it was visually an elegant eye-catcher and was already in the business very well in hand. This first impression has been further confirmed by the ease of installation and I am totally impressed! For my needs (mainly work with word processing and Internet) is more than adequate and at an incredible price (which was slightly lower again in the rest of the business as here at Amazon ;-)).
