The RL-191 is a wired TENS therapy device built for serious pain management at home. With 36 preset modes and dual-channel independent control, it handles neck pain, shoulder discomfort, lumbar muscle strain, and sports injuries — one device for the whole family's recovery needs.

The RL-191 is a dual-channel TENS massager with a high-definition LED display. Each channel is independently adjustable, so two people can use it at once, or you can apply intensive therapy to two areas simultaneously.

The 36 built-in preset modes simulate professional physiotherapy techniques — acupuncture, massage, kneading — matching common pain scenarios from stiff necks to sports injuries. A 25-level intensity gradient lets you progress from gentle soothing to deep physical therapy, adapting to your pain sensitivity.
