Can't fault this Mouse,
For the price I could as for no more. Does exactly what it says on the tin.
Bought it to use with the laptop as I hate the little finger pad. Can use it on the arm of the sofa or in bed or wherever I am. Doesn't respond well to shiny surfaces but then no optical mouse does.
Best feature has to be its range. Quite often we plug the laptop into the TV to watch iplayer, 4od etc. and its nice not having to get up from the chair to control and adjust.
If pushed the only slight annoyance is when you have the laptop i in full screen watching something the mouse, if not placed on a firm surface seems to sense movement and brings up the control options. Easily rectified by placing it on the table or sommat.
In short I would definately recommend.
