Great portable mouse
I bought this mouse in January and I have got to say it is one of the best laptop mice I have ever used. The new nano receiver that it comes with makes it possible to just plug it in a usb port on your laptop and forget about it. There is no pairing issues, everything is just plug and play, although you can install software to customize the buttons to your liking just like any other mice. I tested this mouse on a friends glass coffee table and it worked great. The receiver can also be used to connect different Logitech devices as well to the same one. The battery life on this mouse is amazing, I have been using the same battery that the mouse came with for the past 5 months and haven't needed to change it yet. The bottom of the mouse has a on/off switch which also acts as a protection device for the sensor when the mouse is off. The only con that I have about this mouse is that it is a little bit on the small side (although most notebook mice are), taking that into account this is a great mice for people with smaller hands and/or people that use the claw grip, the mouse is not big enough to use as a palm grip device. That is the only complaint I have, everything else about this mouse is great. 5/5 stars.
