Besides the usual two main buttons and the scrolling wheel on the mouse has back and forth to provide two left-to-use with the thumb buttons. Furthermore, there is behind the scrolling wheel another button, with which you can change the sensitivity of the mouse pointer optional 1000-1600 dpi. Not If you use the mouse for a long time, it is easy on the battery in a kind of sleep mode from which they can reawaken with a simple button click.
Since I spend quite a lot of time on the computer, me is very important in a mouse to fit ergonomically into my hand and enables a relaxed working possible. I have relatively large hands and ours of Rii I use mainly on the go. For people with smaller or medium-sized hands, this model should fit very well. The build quality is decent mouse, as well as the working accuracy.
In absolute terms, this is a good mouse with a great price-performance ratio, which also makes a good impression optically. I think the mouse is rated 4 stars fair.
