Summary: I purchased this for a DIY kit because wanted to use a wired keyboard but not a wired mouse. I like the small usb receiver, and have it mounted at the back of the tower. (it was originally mounted in front - no problem moving it). It is a dinky little thing for my big hand, but it works well and shuts itself off when sitting idle.
Summary: The small USB chip got stuck in the USB port on my new laptop. The support at Gear Head is absolutely terrible. After a few phone calls they told me to take pliers to remove it but that broke the chip and bent the spring clips in my laptop port. Upon inspection, there are holes in the USB chip that locked it into the port permanently. Not the holes on the top that are on every USB plug but these are on the side.
Summary: I love this mouse, I purchased it to take it to work with me. The description didn't state what kind of batteries, this takes 2 AAA batteries, which the package came with 2. Not to forget the little remote part you put in the computer has a place you can place it on the bottom of the mouse. Still trying to figure out what the button on top does, over all GREAT purchase. I love it.!!!
