This excellent product I highly recommend! Our holiday home in Greece is cold and damp to wet, cold winter, because the heated underblanket is a blessing - the best I have never slept there yet. Very well thought out and the mehrstufuge power slider, which can be adjusted if required using the timer. Cable and switch do not disturb, and the little red light is barely visible in the dark. The only downside: getting up in the morning falls twice as much!
