I chose this mouse to TMS, located at that time especially the wrist "impossible
supporting the position of the hand on a normal mouse. "
The median nerve in the carpal tunnel was very fragile, from the 1eres uses
this mouse and another to work the pains dimunués. I do not use it all day for dinner only.
The use of a normal mouse was unbearable beyond 30min Through this vertical mouse I can continue to work in the evening again.
At the hand movement is light, laser fast enough to be paid well.
I was afraid of the size of the mouse because the V4 exite in small and bigger model. No two models for this mouse but easy grip for an adult.
PS: This is only an aid "handy puor continue his job" but is not the complete solution.
