Summary: While this is a great improvement over a basic mouse and would be good for people who have no elbow support while using the computer it is not for me as my desk is U shaped and my arms are supported to take pressure off my shoulders. The vertical arrangement causes a shift muscles in my arm that are used .. aka ones that haven't been used in a while complained .. also my pinky finger will have to develop new callouses and felt cramped.
Pros: Great improvement over basic mouse, Light touch buttons
Cons: Not a improvement over a gaming mouse, 90 degree rotation of muscular control of mouse movements
Summary: This mouse is very nice for anyone who gets any sort of finger/wrist pains after prolonged usage of a mouse. The angle your hand sits at is much more natural than the usual mice, and takes a lot of stress off your wrist. The buttons are nice and responsive, but not quite as nice as my Razer Mamba.
Pros: - Vertical angle really decreases stress on the wrist, - Wrist pain is virtually gone after a week or so, - Speed controls and software definitely a plus, - Love the middle click button (and mouse wheel button can be set to anything you want), - Large mouse that fits nicely in the hand
Cons: - Still not quite the perfect shape, - Wrist hurts a tiny bit in a new spot now, - Takes some getting used to, especially in terms of how to grip it, - A bit too pricey
