I usually run the electric blanket in the cold winter months with my back in bed. The temperature is fine although I have mostly operated at the highest level. The size would be me personally nearly enough, though I buy the new bigger now. The major shortcoming of this blanket is that you can disconnect the cable at both ends, ie plugs and cushions each other. The consequence of that if you do not meticulously paying attention that the plug is inserted always right on the panel, it comes off a little and then it is, for example, smuggled me to. With an electric blanket so I will of course can not sleep in peace, and I will have to change. The company Breuer I trust with electric blankets, so I'm going by the company another model, which is somewhat larger and perhaps has a bit more comfort, buy.
