For large hands absolutely inappropriate ...

Its idea is not bad, but really thought poorly.
With big hands, this mouse, at least for me, absolutely unsuitable.
Even if I'm raising the palmrest all the way back, I still can not touch this sensible mouse, at the latest on Seitwerts movements stumbles this either on my thumb or on the right two fingers.

For my right hand this object is clearly in the category of medical devices, it will be compelled to perform acrobatic finger exercises ...

Programming is simple. But, the keypad is useless for me, I hit at least 2 buttons simultaneously ..

Would not be my wife for this "Mini Mouse" interested, I would send it back ....
