It has three different heat settings.
The 3rd stage I would compare it to a classic hot water bottle.
Especially in winter, when a stomach ache, neck pain, back pain etc. wonderfully usable.
It's not too big and you can super position on certain parts of the body.
In the winter I would not want to miss it, because it is precisely the coldest time of year it has done me great service. On the couch under a cozy blanket, reading for example, it is really wonderful warm.
Often I could not sleep because I had icy feet, then I got me the pillow placed on the feet and was finally able to sleep in peace - this is the automatic turn-off function, which switches off the heating pad after 90 minutes, really convenient.
If the cushion is once become dirty, you can simply remove the cover and wash in the machine, then it is like new again.
