The pads can be used for weeks at a time. The key is to keep them clean and moist. As such, it's important to place the pads onto the pads carrier once you are done so that they don't dry out to air. However, even if the pads are a bit dry or dirty, you can always get them back to stick by wiping them clean with a damp cloth. Also, please note that the eKegel already comes with 4 counts of each pad (perineum and coccyx), which should last you months, especially if well taken care of.
