Pros: According to CNET, this mouse has a three foot range, but my own experience with it begs to differ. I have used it at about a six foot range, and it functions just fine; and unless you're pounding it with a hammer, it's not going to break easily.
Cons: The only complaint I have about this mouse is the USB reciever is a little long.
Pros: I bought this mouse because it was on sale at Wal-Mart for $19.88. I was going to buy a Logitec wireless optical mouse, but I got this one because it was on sale, and the Logitec was $34.99.
Cons: you have to go to http://www.microsoft.com/hardware to get the software for it. on default, The center button is set on some weird mode that did nothing, so i had to manually put it on Click Scroll for my Internet Browser.
Summary: This product uses a jump-drive-size USB attachment. When the mouse is not in use, the USB attachment fits into a niche on the bottom of the mouse, and shuts it off to save the battery. It works quite well for a wireless mouse, though is not as precise for locating objects in a graphics program as my wired mouse is.
Pros: Accurate Tracking, Battery saver, Comfortable Design, Fast Response, Glides Smoothly, Works On Any Surface
