LOVE IT! LOVE IT! LOVE IT! The minute it arrived I put it on and felt instant relief and comfort. I went to the garden and worked twice as long as normal. I'm a female with a 36 inch waist - the belt fits beautifully. If you have lower back pain, give it a try. A similar device that didn't fit well cost me 3 times as much at my local medical supply store. You can't go wrong!
