With 6 stages you can regulate the heat supply wonderful. After about 3 hours the blanket will automatically turn off so it does not overheat. However, it is not a problem, just back on. So should forget to switch off the ceiling you get, that's not bad, because it goes on its own from.
The ceiling is super big, so can cuddle 2 persons including without problems. In some reviews I've read before purchasing that only a small portion of the ceiling would be heated. Of course, it is not heated to the brim, but in my opinion but the Größtteil the ceiling. No matter how I cuddle into them, I will always be warm. Another positive is that the ceiling, compared to other electric blankets is relatively thick.
The only drawbacks are the ceiling, on the one hand that it has extremely gefusselt beginning. We own the ceiling now approximately 1 month, the fluff has subsided. That was at the beginning but really annoying because you got the little lint from the clothes or the carpet removed. On the other hand, we noticed that when it is a bit tangled, especially when one is alone, including in it "wraps", the heat is no longer evenly distributed. The heating wires are apparently bent, so that the heat in this will no longer be forwarded. This is the ceiling in some places very warm and at other places not. So you should make sure that it is not too much geknäult in some places.
Nevertheless, I can only recommend this ceiling. I do not know how I would survive the cold winter days without them. ;-)
