A really good Mouse that fits to the hand well and i have found that it works on just about any surface so no need for a Mouse mat.

For the price, this is an ok mouse and much better than constantly feeding with batteries. It does sometimes see to have a life of it's own and dances a fandango on the mat occasionally but I think that's me gripping too tightly while playing solitaire. I think it's ok.

This is a very simple product that fulfils a very simple function and it is very good. I have only had it for a week but I must say that it is working well for me. It is very cheap and exactly what it needs to be. I would recommend this if you are looking for a cheap computer mouse but you want value for money.

I have to say that I was rather disappointed by this mouse as I had great respect for Logitech products. However, it has already ceased working after only a short lifespan. This may have been due to the fact that I use it for doing jigsaw puzzles and playing Solitaire and, if so, perhaps someone would enlighten me! I have now put the previous mouse back into action.

The logitech M90 is pretty much the same size and shape as the Microsoft Basic Optical mouse. It tracks fine, worked almost immediately after being plugged in but there are a couple of niggles. Firstly, the scroll wheel isn't as smooth feeling as the Microsoft one. it feels differently depending on the scroll direction: it's more 'clicky' when scrolling from top to bottom and, in reverse, it feels a bit rough with less of the 'clicky' feel.
