The reason why I bought this mouse is because the previous mouse (A4 tech) which I was using died on me after three years of usage. I was scouting for something simple and nice, I came across this.
One thing you have to take note is that, the product advertised in Amazon is different from what you received. Althought the design is just slightly different, nevertheless this is still a great mouse.
It's very light, and hence, it's easy to be carried around or even to chuck it inside your bag. It goes well with both of my laptops (for HP and Samsung netbook).
In terms of the mouse pointer and tracking surfaces, I do not have any problems with it. It's pretty smooth and accurate. The scroll wheel and the buttons are not too noisy. However, if you intend to use it in a library where total silent is required, I wouldnt suggest you use the mouse, but instead, use your notebook touchpad.
This mouse is very durable as well. I've once dropped it on a concrete floor and it still works perfectly fine. You can try dropping it a few times, to test how durable it is.
All in all, I've been using this mouse for four months now and am very happy with it. For those who want something simple, light, compact & non-hardcore gamer, this is the mouse for you.
