I tried the ergonomic mouse by accident. I immediately felt something different, so I do not have TMS. Looking back on my regular mouse, I felt increasingly gené. After a few days I decided to buy this cheap model. And the magnitude of change goes beyond what I expected. Not only discomfort associated with conventional mice disappeared, but the use of this mouse makes use of the very nice computer, and oddly beneficial for the arms. My wrist like the rest of my body are relaxed by the use of the mouse. I make the strange conclusion that most of our everyday objects are not really suitable for us, they are helpful but not more, not fun to use. I can not yet judge the longevity of the product.
