This purchase was to replace a similar size product made with oats called a Comfort Bag.  It works the same and I use it warm to relax my neck muscles without having to worry about falling asleep with an electric pad.  The only thing I miss is the removeable/washable flannel cover that came with my old bag.  I would recommend the manufacturer add such a cover with the product which would have made me give it a 5 star rating.
