I recently bought a mouse of laser (made by MobileGear) for my portable computer of Vista, but being a mouse of laser, that does not function as good as it would have, particularly on the surface of glass. Perhaps one of the reason is that because this mouse is not Vista-certificied, like Zoffy. Yes, weighs with Juste 20 grams and has a precision of 1600cpi with 6700fps, this mouse, unlike mine, is claimed like device of entry Vista-certified by the manufacturer! A trick si’ futé’ of sale since the majority of the mice would function correctly under Vista
