If you're not experiencing any stimulation during your therapy session, it could be due to a few reasons:

1. Check to see if the cover still over your Therapy Pad.
2. Is your Therapy Pad placed directly on your skin?: Make sure to place the Therapy Pad directly on your skin. For the best results, please place the Pad directly on the targeted area of your thigh. Review more placement informaton here. 
3. Are you using Conductive Gel? - How to apply conductive gel: Apply directly to the skin area where the therapy pad will be placed. A small pea-sized amount of Conductive gel will be completely absorbed into the skin (not a thick layer). Conductive gel helps dry skin for a better stimulation session.
4. Therapy Pad - Our therapy pads need to be replaced after 14 uses. For more information please review this article here.
