This neat little mouse was part of the Tesco 3 for 2 Christmas presents some years ago and so there are a lot out there. But it's small price tag is not to be mistaken as a poor quality product. it's not going to be able to rival the best of the business but for basic users it's fine. It's also stood the test of time in that it's still being sold.
It's simple fit under the palm of your hand size and understated black and silver makes it perfect for business travellers. The end of the large silver part is pressed once for the USB fob, which pops out a good distance with a nice little click. The back of the mouse then slides off to reveal space for 2 triple A batteries. The batteries make it quite weighty for such a small unit. Apart from that it's a normal mouse, click down scroll whell, reset button on the base, and bright red optical light that shines through the scroll whell too.
It works fine. It's got a relatively short inactivity switch off time.The lit wheel makes it easy to spot when it's in use, dimming when it is idle and going off when it's switched off. Clicking any button will put it back into action. The range is sufficient for most basic laptop users, working perfectly for the first 50 cm or so. The more electrical gadgetry you have the less responsive it becomes. I've never got it work at any great distance from the computer, which is a shame as it would be so useful for presentations and watching films!
I find it jumps easily, with my usual setup, but not enough to not use it as my main mouse. The way the USB fob fits inside and will work on just about any USB port, even hub plugged into hub, is a great bonus. I'd never say it's amazing but as a nice neat travel companion it's served me well the past few years.
