With significant pain in the hand, arm, shoulder, (and head, lark ... it was almost that), I tried to improve my position and found this mouse model priced gift, impressive compared to the prices of other ... I'm easily 6 to 8 hours or more a day on my computer is my main activity. By buying it, I thought "middle way." For over a month now that I use, I find that my most significant pain have faded, my hand works with the well positioned thumb, I feel much better. For me, a huge progress. I really recommend this LuguLake Mouse.
