This underblanket is super !! Finally, why bother with hot water bottle that warms eh only selectively. Switch Easy 10 min. Before going to bed and then feel comfortable. It could not be any more. Also recommended for back pain sufferers. The muscle relaxes and it helps. I would buy the product again. By programming the heat levels and duration of the heat it can be adjusted individually. Just a great product are ... When I've still had no problems ... this Wärmeunterbett does not bother me while lying. So far, I'm absolutely positively surprised.
