The heating pad is a total disappointment !!!! Unfortunately, it will not really warm even on the skin direkt-- hardly spĆ¼hren - not even at the highest level !!! - The figure is deceptive, it is too short for an adult - and not enough to the lumbar area !!! --In shoulder area it is not hot not even a bit !!! No purchase recommendation !!! Enigmatic the postiven feedback is me about this product? Can only be that the product exsistiert in varying quality.
