Review on 🔌 Beurer EM38 Lower Back Pain Relief Belt with TENS Unit Muscle Stimulator, 4 Electrodes, Adjustable and Breathable - Suitable for Women and Men - Waist Size 30”-55” - Provides Lower Back Support, Lumbar Support, and Back Brace Belt by Rashid Summers

I have had severe back pain recurring to the point where my legs and feet are always freezing and my feet are numb. I first put the belt on 20 and was like, hhhmmmm, I don't think that's going to help much, but I'll leave it on and see what happens. Well, let me tell you! Phase 2 starts in 10 minutes and will curl your toes and hair! Holy Camoli! Don't do this, and I repeat, DO NOT turn all the way to 20 because you won't think it's strong enough. Believe me! Maybe switch to 5 first and let this phase 2 begin before making any adjustments! Wow! If you have severe back pain, these are the dozens for you! No wires and works great!
