This is the best item I have purchased in years. A quality product. The under blanket fits the double mattress perfectly and the side nets hold it firmly in place. The controllers are spot on with heat range from 1 to 9, and the timer 1 hour through to 12 hours. The electrical socket on the blanket to which the controller attaches is well positioned and not noticeable when laying in bed. Being only 60 Watts the blanket ideally needs to be switched on about an hour before bedtime in cold weather in order to have a hot bed to climb into - this is quite normal and was the case in the 1960's when I last had an electric blanket. I cannot fault this product and have no hesitation in recommending it. Ordering the blanket via the Homefront website was simplicity itself. I ordered it around midday and it arrived mid morning the following day, now that's what I call great customer service.
