I purchased this product a while back and tried it out twice. First thing first, THIS PRODUCT SMELL!!!When I first used this product it wasn't that bad but after 20 min or so I had serious neck and back pain. I had to take out some of the air and made a pillow out of it leading against the window. It was okay but was not as comfortable as a normal pillow.On my second time, this product was useless peace of junk. Air keep leaking out.To me, this is more like a one-time use of a no-good-pillow product.
