Our most portable and smallest unit contains a single LED with both a "solid" or "continuous" setting for pain relief and a "pulse" (266 cycle) setting to accelerate recovery.
It is powered by a 9-volt battery, which can last for 20 hours (approximately 4-6 months of use).
The design is ideal for use on acupuncture points yet it is still powerful enough to be used on the skin surface and for effective penetration of 1 to 2 inches beneath the skin.
The small size (4 inches long and 1 inch in diameter) makes it easy to carry in a pocket or purse.
Safe enough for children to use.
Cannot be over-used.
