  • Our take on the Omron PM400 Pocket Pain Pro TENS Unit

    The Omron PM400 Pocket Pain Pro is a battery-powered TENS device that sends low-level electrical pulses through electrode pads to dull pain from arthritis, fibromyalgia and other chronic conditions. It is small enough to clip on and carry, with adjustable intensity, several massage modes and a timer for sessions. It suits people who want drug-free, at-home relief for everyday aches and are willing to place pads themselves. Against rivals it is simpler and more pocketable than multi-channel clinical units, but it offers fewer channels and programs than high-end models.
