Now to my review.
The heated underblanket is great.
You notice no heating coil, fine workmanship.
It has a pleasant warmth, you can regulate super and the best part is the timer. They must not be switched off before going to sleep and then gets cold feet still. No, to sleep snug and warm no later waking wg. a heat shock.
Really great !!!
Also fits mattresses 200x100.
Am completely satisfied. Your money's worth.
