Great little mouse, just wish that it was bluetooth so that I didn't have to use the dongle on my laptop.

Dongle hides in mouse; Has side scrolling; Works on any surface

A little expensive; No bluetooth; Only one side button

Priced in the region of £35, the requirement for this mouse is any system capable of running Windows XP and later with 100MB of hard disk space or Mac OS X 10.4 with 30MB of hard disk space.

Compared to the price you pay, it is good purchase. Its looking from the picture is better than what really it is.

Has been working great ever since I received it. Battery life is long and efficient and it has its own port to place the USB Bluetooth hub for easy storage when not in use. Batteries are included so that is also a plus

I've tried, butnever been able to ditch the mouse and use the touchpad exclusively. I used to buy expensive Logitech mice, and each time they would fail after a year. The computer support person at work recommended the Microsoft mouse. I had my doubts, but he was right.

I am not sure of this is worth the money. It probably is but did not quite provide the extra difference a premium mouse should offer. There is nothing wrong with it; more nothing especially right with it. The fact that it is better than OK probably means I am being fussy.

Computer mice are easy to take for granted. Very rarely do people gloat about the power of their mouse like they would about a processor or graphics card, even if they have a nifty device like the Hillcrest Labs Loop Pointer or SideWinder X3 from Microsoft .
