Negative Positive
Title: Not ergodynamic
Review: I'm starting to have pains in my wrist/forearm from using a mouse. Thought this would make wrist and/or forearm feel better. You have to press the enter button with your thumb with enough pressure that by the end of each day, I'm in significant more pain than before. Just switched back to my old trackball...pain gone. Bummer I liked the features but the pain is a dealbreaker.
Is the review positive or negative?
