Comfortable and Healthy: The gel pads are made of high-quality materials, and the EMS pads are less irritating to the skin, providing a safe and comfortable experience. They are also highly adhesive, self-adhesive, and reusable. EMS Gel Pads: Replacement gel pads for EMS muscle stimulators, compatible with various EMS devices. Featuring 0.8 mm hydrogel stickers with high conductivity, they ensure close contact between the skin and the EMS muscle stimulator for effective performance. This size fits most standard electrical stimulation units. Long-lasting Viscosity: Professional-grade muscle stimulation gel pads offer extended service life and can be used approximately 30 times. The actual number of uses may vary depending on skin cleanliness and oil levels. For best results, clean the skin with alcohol before each use to help extend pad life. Note: Replace the pads with new ones if more than one month has passed since opening. Maintenance: Before use, ensure the skin is clean and dry. Cleaning the skin with alcohol is recommended to maintain pad adhesion and prolong product life.
