How many times can I use the pads?

Zense pads are made out of hydrogel that sticks to your body. Our pads have a longer than usual usage life- approximately 20-30+ applications. However, if you want to maximize the life of your electrode pads, we recommend that you always clean your skin before placing them on your skin. This will ensure that any creams or lotions you have used are not transferred onto the pad itself. We also recommend that you clean the hydrogel area of the pads with a wet towel and let it air dry to help restore adhesiveness and maximise usage life. Other things that can affect pad life expectancy are your skin type, body oils, and pH levels. When the time comes we have very affordable extra pads that you can purchase from us at any time! 

How can I use the TENS device to maximize its efficiency?

Our Zens tens/nmes products may be used on most areas of the body, except on your neck, head, or chest area. 

Please view our full guidelines for optimal pad placements here.
