We got this Windows Vista Compatible Mouse with the purchase of our HP Compaq Laptop. But it had a price tag with it and it costs $6. What I noticed about this very mouse apart from all the mouses that we have is because primarily, it is very attractive. It is rather squarish and the wheel is lighted in blue, apart from the red optical sensor, that while my husband was working on his laptop, I could not resist the urge to touch the wheel and move it, not mindful of what may happen to what my husband was working on.
Anyway, the mouse is a little smaller than usual and fits my small hands perfectly. It is supposed to support the contour of both left hand and right hand users, but since I am right handed, I don't mind at all. The scrolling is soft and quite silent, as my old mouse is quite noisy, like I don't use it to scroll much when my baby is asleep because she is awakened by the sound of the scrolling.
I really like this mouse, if mouses aren't given out for free, I would buy this one. My husband offered to exchange mouses with me, but I was ashamed so I let him have it. Its a good product.
