I required two computer mice for my my laptop and my wife's machine. I did all the usual reviews/searches and decided I wanted the nano type mouse and settled on a Logitech. However, when I checked the prices I was astonished - anything from 30 quid each and upwards and not much cheaper in the States where I go occasionally.
I then saw this mouse on Amazon which was receiving great reviews. I went for it and the two items were delivered in two days - including free postage.
The mouse is sized between a small laptop and the normal size mouse. Very light to handle but the construction is ok. Worked straight from the box and is very fast. Bonus is an on/off switch on the underside of the mouse which means you can leave the little nano receiver plugged into your PC USB port and merely switch the mouse off when you are finished with the computer.
Nothing much more to say other than I consider this a great buy and would highly recommend it.
