Natural: Transcutaneous Electrical Nerve Stimulation (TENS) technology has been used by doctors for more than 30 years. Gentle, continuous and at your preferred intensity, our TENS unit's dual channel design allows for customizing intensity levels (up to 20) for each pair. The electrical pulse stimulation triggers the body's natural endorphin response to block and relieve pain while stimulating the tissue to regenerate, all without the use of any drugs or chemicals.

Portable: Compactly sized and weighs less than a tenth of a pound. The unit is rechargeable (both a USB cable and AC adapter are included) and can be taken and operated virtually anywhere so its therapeutic power is always instantly at your fingertips.
