LifeMax TENS Machine digital painkiller

I’m not sure if a machine can actually provide any pain relief as I thought that was always the domain of painkillers, but the LifeMax TENS Machine claims otherwise with a promise of delivering pain relief, body toning, and massage. The LifeMax TENS Machine comes with a dozen preset programs, 2-channel user defined programs for different needs, and four reuseable treatment pads. This sleek silver device measures 63mm x 145mm x 20mm and runs on a quartet of AAA batteries. I suppose the science behind Transcutaneous Electrical Nerve Stimulation (TENS) has something to do with pain relief, but you’ll have to pay £29.99 to find out for yourself.
