This mouse is the one I use with my netbook when I'm using it at a desk or table, because I much prefer to use a mouse with it rather than the touchpad, which I find too small. I originally bought one of the "mini" mice on a retractable cable, but in truth that was too small as well, so when I spotted this one in our local computer shop I bought it - it was sold for £5, as "almost new", and still in its box. The mouse is currently on amazon for £3.01+p&p so it's worth shopping around, as ever.
There is a great look to the mouse with the "anthracite" main body of the mouse being glossy and polished whilst the sides and centre strip is a matt black plastic, giving it a nice classy look.
What I immediately liked about it was it's size in my hand. This mouse is definitely the "in between" size - not as big as my desktop one, but doesn't feel like a miniature one either. It's dimensions are 10cm long, 3cm high at its tallest point, and 5cm wide at its widest. It's ergonomically designed, so quite curvaceous and sits nicely under my hand. Obviously at that point I should make it clear that my hands are quite small, and so to a much larger hand I can envisage the mouse could feasibly feel quite miniature - it's definitely noticeably smaller than a standard PC mouse.
This is a simple "plug and play" mouse, there is no installation to go through, and it is recognised and up and running in moments on all the computers I've used it with.
The mouse is an optical USB which means that it's connected via USB to the netbook, and it controls the cursor by means of a red LED sensor underneath. The cable is 70cm long, which is quite long enough without being in the way.
The whole of the body area is moulded, you just click in the appropriate area at the front rather than there being a physical button. The centre wheel is small, only about 1.5cm and recessed into the body of the mouse, all cleverly designed for really comfortable use. It's a click wheel which gives another useful aspect to the mouse, pressing the wheel enables easy scrolling through large documents.
I'm no computer buff at all, so can't convey technicalities in terms of its spec and its sensitivity. I can only report that being that it's never let me down or had any mad moments of jumping or wandering cursors. It's very responsive in terms of moving the cursor as well as the clicks. The click buttons are quite therapeutic to click with a really gentle sound and the wheel is easy to roll and click without needing to adjust my grip. The mouse works easily and reliably on all surfaces other than glass, including without a mouse mat.
