I see all the other enthusiastic reviews and wonder a little. The heating pad has my expectations anyway disappointed ganzere line. It is of course not be excluded that this is a Monday device and the thermal sensation may also differ from person to person. But a precaution should be spoken at most of a heat, instead of a heating pad. Who tidy expected heat like Grandma's old Bakelite pillow here, will definitely be disappointed. In my view, the Wirkunsgrad so low that you take this cushion can also simply take a warm blanket.
