I've been using this mouse now for about a month. It was easy to set up with all the adjustments explained fully in the instructions. It does do what it claims to do--reducing the stress on my wrist and hands. By being able to adjust the angle of the mouse it means that I can adjust it on a daily basis and I am finding the stress on my hand has been greatly reduced. The only con with this is that it doesn't show when it is fully charged, but it does hold a single charge for more than a month. I would recommend this mouse to anyone with Carpal tunnel or Trigger finger as it has been a great help for me with these ailments.
