Comfortable for back and belly aches
I bought this product as I experience low back  ache and stiffness from arthritis and surgery of the lumbar spine. I was looking for a product that would be easy to use that I could wear to warm up my back prior to exercise. This works perfectly. The Velcro band that goes around the waist is fully adjustable and my waist is about 29 inches but there is plenty of extra room for someone larger. This product also serves double duty as a belly warmer for stomach aches. It is easy to remove the pouch and pop it in the microwave to heat it up. The heat lasts about 20 minutes.  I felt the price was perfectly appropriate for the product.
