I have often times back pain or neck, so now had to finally restore a heating pad. I am very pleased with the Beurer heating pads! There are very warm at the highest level, but not too hot. You can take the pillow well with the bed and start at the highest level if you want, it peels off after 90 minutes of alone out. The envelope is the nice and soft and nice color (looks as in the illustration). They can close with snaps. The pad does not slip in the envelope around as my old heating pad did this, but it remains in place.
