"I will start off by stating, I have used a regular back brace for many years off and on due to working construction building custom cabinets for 12 years. When I start feeling pain in my lower back from leaning over too much at work I have always resorted to using a back brace which works but only for a short amount of time. With this heated back brace it eases the pain much longer! It actually forgot that I was even having any pains for a little while. I was a little unsure of the battery on the belt being uncomfortable but don't be, once I put it on I never even noticed it was there. Well made and had no problems with the battery slot, battery cable, or getting it to work. I never write reviews good or bad, but this helped me be comfortable at work and at home so I couldn't help myself!
