I Love this Bluetooth mouse, it free's up a USB port. Works perfect on my MacBook Pro with Win7.

Actually the tracking and buttons felt excellent. And the thought of freeing up a USB socket was great, however, the mouse would intermittently (30-60 mins) break Bluetooth contact. Not good for a gamer. I would have to re-pair the device.

This bluetooth mouse works great....linked right in and has been very consistent.

Excellent mouse to use with my Laptop.

I bought this mouse because it had the best battery life of all the mice I reviewed. So far, the original batteries have already outlived the mouse I was using previously. I will be happy if I get even half the battery life out of this mouse that is specified. All in all, a good purchase.

Quick to connect, fast on, shutoff switch; Hoping battery life is as good as specified

A bit of difficulty opening battery compartment; Centre button is useless for MAC OSX

Got this because my expensive microsoft wedge couldn't cut the mustard. Installed easily and no trouble since. Highly recommended.

Nice to not have a receiver plugged into my limited USP ports on the laptop. Works well.... paired instantly. Happy so far.

The Logitech - 557 mouse was easy to configure and it works as you would expect. The Bluetooth feature has a perfect operating record in the 3 + weeks I have been using the device.

Sometimes I just like the familiarity of using a mouse rather than the touchpad. I've had it about a month and it seems to holding up very well. Great for traveling with your laptop; it survived TSA and gate checked baggage.

Incredibly fast response - have an older blue tooth and this one is much better. Occasionally loses connectivity on start up, but I keep the bluetooth icon on my desktop and just click on it to bring it back to connectivity. Am replacing other mice on two other computers.
