The Uno is a single PowerDot that allows you to stimulate one side of the body at a time.

The Duo is a pair of PowerDots allowing the user to stimulate both sides of the body or multiple muscle groups at once. With double the pads, Duo cuts your usage time in half while extending their life span. You'll cut down on the number of applications/re-applications to treat any one area.

Either option allows access to all of the pad placements, programs and modalities with the exception of “Long Haul Flight” (only available for Duo use).
