Summary: The concept is really innovative. Imagine it: your wireless mouse is low on batteries... and you just do not have time to get batteries, or you are not in the most convenient place to get them... and instead of reverting back to your laptop track pad or an old mouse, you easily could take the cover off this mouse, pull out the USB cable, and you could use this comfortable, fashionable mouse!
Wireless went out after batteries died - now it's a wired mouse

Summary: I bought this at Circuit City before they went bankrupt. For a while, it was a great mouse - worked well, wireless or wired, and it wrapped up nicely for storage (although the USB cord is a bit tight if you have to re-wind it). Eventually, as was bound to happen, the batteries died. I replaced them with a new set; no problem. Later, when the second set died, however, the battery-operated functionality failed.
Summary: I have used this for 2 days now - the first day I ended up borrowing a friend's Microsoft wireless mouse (which worked flawlessly) because my 2 hour old Kensington was falling apart (there are 3 magnets inside holding the case together, 2 of mine came off the first day). I glued the 2 magnets back on that night, and the second day was better, but after using it for about 15 minutes, it would start flaking out and I would be unable to select anything on the screen.
Summary: I bought this mouse as a Christmas present for my mom. It is a great looking mouse and the back-up USB feature is great. It worked great at first but after about 9 months of use the outer rubber (the black covering around the entire mouse) covering and the rubber covering around the scroll wheel began to melt off, so we ended up just having to tear the whole outer covering off, leaving an orange plastic cover.
Summary: The mouse and RF receiver work well as a "standard" 2 button mouse. The Kensington MouseWorks 6.2 software will not function on my W2K-SP4 system. Because of that, the scroll wheel button can not be programmed to perform any function. Even the driver for my corded 3-button mouse will not recognize the scroll wheel button on the Ci75. So I cannot perform a double-click with the middle button, which is a major pain, and I will probably toss this mouse in the garbage.
