The Mobile Mouse from Microsoft is, as its name suggests, was probably built more for mobile use. It is not too small, but big hands tend unsuitable in order to work longer hours. In her hand she is well and feels stable on. The glossy "piano lacquer" elements evaluate the optics on yet. If the range was at 3m not yet final, can the computers you need good use from the sofa, for example via TV. The nano receiver is really tiny and barely stands out from the USB socket. Unfortunately, no indicator light is on the mouse, so that turning off overnight and can be forgotten times. Only the red glow of the image sensor on the bottom reveals the operational status. The scroll wheel is virtually noiseless and the clicking of the keys has a standard volume. The mouse is powered by one AA battery. Overall, thoroughly recommended.
