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.

ergonomically sound and works through a timber wall

would be great if it was rechargeable; instead of needing batteries replaced a albeit very rarely :

I bought this not to long ago and it's still working beautifully, easy to use and has great features

I needed a bluetooth mouse for my tablet and this one definitely fits the bill. Slimline, very comfortable. A great improvement on my old USB mouse.

I have tried several fixes, but this is a Linux specific bug. Had I used this on a Mac or Wintel (MS Windows), it would work automatically. So, 4 out of 5 Stars...

Works out of package with Linux Mint 18 "Sylvia" Cinnamon Distro

A wired mouse is needed to manually turn on bluetooth every time my computer is restarted or when logging back into system
