These are nice to have arround. There used to be a varsion made by sunbeam and the outer plastic packet was a heavy vinyl that seamed more substantial than the one you reviewed. I also had one that was about 8″ by 18″ and partially subdivided to wrap arround a shoulder eaiser. BTW if you kind of kneed the packet as the reaction is starting you can get a warmer initial temperature.
