I have always had back pain when I work around the yard, so much that after a few hours, I am stooped over when I walk to reduce the pain. With this brace, I was pain free for four hours of strenuous outside labor the first time I wore it. Same result for the second time. I was also impressed with the security of the hold given by the velcro fasteners. Even with maximum pressure on bending over, there was no sign of the fasteners giving way and loosening up. I highly recommend this product.See full review
