This review is from: Microsoft Wireless Notebook Laser Mouse 7000 (Personal Computers)
I've got one of these, i've tried it on the back of a chair, at the other end of my room, six metres away diagonally to my pc AND i've tried it in a different room it still works even with objects in the way of the signal due to it's 2.4Ghz wireless signal.
It also has programmable buttons and a magnify option.
Very easy to install.
Hope This helps.
P.s. Mine doesn't squeak.
