This is a vertical mouse that’s designed to limit wrist strain during extended computer use. I think it’s an excellent way to optimize daily tasks that just makes sense, since traditional horizontal mice and touchpads are not designed for the natural wrist position. I developed wrist pain last semester after years and years of spending inordinate amounts of time on the Internet, coding, and doing design tasks. Even if you don’t have wrist pain, it’s a smart way to prevent it and avoid carpal tunnel if computer use is a significant part of your daily life.
