Rarely do I rate products online but this Theracs decompression belt deserves to be rated. I was experiencing extreme pain in may back due to L3 - L5 and T11 degeneration. I purchased it on a Friday and received it at my home on Sunday. Put it on and within 30 minutes I was feeling much better. I have used it for a week now, for about 3 hours a day and my back pain is essentially gone! You don't have to wear it all the time, about 30 - 60 minutes twice a day works for me, but I wear it anytime I am doing any lifting or physical work. The only down side I can report is that, while wearing it, you cannot bend as easily to pick up things, but that is a no-brainer trade-off for the relief it provides. If you are suffering from pain like I was, this belt is sure to provide the relief you're looking for.
