Really relaxed working

My wife had problems with tension in the neck during long computer sessions. This relatively cheap mouse should be just a test.
The result has surprised me but then: The mouse makes a pretty high-quality impression and it really seems to help against the tension.
When I sit at her computer, the mouse is a bit strange, but not unpleasant and it really comes down to immediately cope with it. It fits here both to the pretty little hands of my wife, and to my hands with glove size 11th

Only to take away it is not so great, because it (due to the shape) is quite large.
