Relief on sciatic nerve.
I have had problems with nerve irritation in my legs from pressure. I don't have enough fat in those areas. Helps cut down on sciatic like pain. Good product exactly as described. Fast shipping.<br /><br />This is an edit to above. I gave the product the benefit of the doubt. It was not like the  ad photo. It was flimsy plastic with blue water and some little soft plastic beads inside. Where pressure was applied, all liquid shifted to another section. Like sitting on a balloon half full of water. It also started to leak after the first week and I only weigh 190 lbs. Flimsy and not gel filled.
