Adopted on the top of the main unit to reduce the strain on the wrist from long hours of PC work. By using the highest quality support balls made of ruby and with a carefully selected smooth surface, the feeling of throwing the ball is greatly improved.In addition, the large support ball makes it difficult to handle.
Not connecting. My comp' found the dongle (has to be plugged in the USB port for mouse) but the Huge isn't responding. If I can get it to work through drivers, I'll change my review. Until then (or if) it's a paperweight.
