Flex Belt Gel Pads last about 30 sessions. The success of your toning session relies on the quality of your Gel Pads. When it's time for new Gel Pads, be sure to have them on hand so you don't miss a day of toning while waiting for new Gel Pads to arrive. We recommend adding an additional 2-3 sets to your order. You can always order new Gel Pads later if you don't want to get extras now.
