Tens Unit Muscle Stimulator Full Body Drug Free Pain Relief Therapy Circulation Massager 24 Massage Modes Life Time Warranty

I was going to physical therapy for sciatica which was affecting one of my legs to the point I couldn't walk or stand for long periods of time. During my first visit the therapist used a tens unit on my back and leg. I jokingly told her that if I could only take that unit home, I would feel so much better. She then told me I could purchase one. I researched different models and read numerous reviews and decided upon this one. I have been very satisfied with my purchase. I have since purchased a second one for my uncle who was in so much pain he had began walking with a cane. It has helped him tremendously as well (no more cane). This is not an overnight miracle but it definitely works to sooth those muscles over time. A little complicated to figure out, but once you do it is awesome. Batter life is great and I love the compact size. I did get some type of cover with mine that looked like a cellphone case. It didn't fit my unit, but I didn't really care about that.
