This mouse is a great buy at such a reasonable price. Admittedly it's not going to stand up to gaming requirements but for home office use this is just fine and dandy. The mouse is easy to hold and the buttons are satisfying to press, no tinny clicking or dodgy side movement. The only thing that is a con about this mouse is the size of the USB transmitter. Admittedly this is a pretty old model, so one ought not expect the latest and greatest nano technology, but be aware that it does stick a fair way out from your USB port.
All in all a real bargain buy, that is performing as it should… what more can you ask for for $25?
