It is a bit uncomfortable to hold and personally, I am bothered by the feeling when pressing the keys and the noise. However, considering its price, I would recommend it as it glides smoothly on any surface and the battery life (1 AA) seems long despite the lack of an on/off button.

Mouse exclusively for bed/sofa, for scrolling and pressing play on a movie/series. Not at all convenient for a main mouse, but it does its job and more. It doesn't need a pad, you can scroll on yourself, it moves on any surface you put it on, for me it's value for money.
