Used under normal circumstances, a BewellConnect® electrode pad should last 15 to 20 sessions. The lifespan of the electrode pads will depend on skin type, hair, etc. as well as where they are placed on your body and the type of care used in handling and storage.
If the gel of the electrode pads no longer properly adheres to the skin the app will not be able to maintain a connection and you may get a warning to check the connection. If moving the electrodes does not fix the problem or you are getting an uncomfortable sensation upon stimulation this may be a sign that the electrode pads need to be replaced.
To keep your electrode pads in good condition and in order to practice good hygiene it is not advised to share electrode pads.
