Billions of dollars are spent each year on carpal tunnel syndrome lawsuits and related cures. We believe one of the contributing factors to developing carpal tunnel is in the traditional "flat-shape" computer mouse design which requires that our fingers stay in an extended position. This is not comfortable or natural especially when using the computer mouse for long periods of time. With the "sphere-shape" design users cup their fingers naturally around the ball rather than extending them outward for a more natural, ergonomic feel that translates into superior performance.
