I purchased this mouse for my laptop as I just can't seem to get to grips with the touchpad. I just love this little mouse! It is indeed very small and lightweight but is surprisingly comfortable and easy to use and means that I can work effectively and efficiently on my laptop when I am travelling. I have had the mouse for 6 years now and it is showing no signs of age, despite extensive use. With the retractable cord it fits neatly and snugly into my laptop case with no chance of entanglement. I love it for travelling and wouldn't do without it but a larger mouse would be a better choice for anyone working for perhaps more than 2-3 hours at a time on their laptop.
