This electric blanket came so fast! Just in time. It was so cold last night and supposed to be tonight. I immediately started unpacking the box as soon as it was delivered today. It was very well packed. (Double boxed)! I took the blanket from the box and opened the vacuum sealed bag it was in. It is so soft! I loved the color. White on one side and grey on the other. As I unfolded I checked to see that dual controls were there. They were! I couldn’t wait to try it out so, I laid it over my King sized bed and plugged it in. It heated to high very quickly. The controller has up to a 10 hr. Auto off feature. It also has a preheat function. Which is great for my husband. He likes to warm the bed then turn off. I like it on high all night. So thankful for dual controls! I am so excited to use later tonight! We will see how it performs. I don’t foresee any problems as I had it on for 3 hrs and still was holding the heat. I am very pleased so far with this blanket.
