I used the blanket several times, but it stopped heating up properly. Only one half warmed up, the other half stay cold. I ended up staying for 3 hours in the blanket waiting for it to get warm, and it still didn't. This isn't to mention that I went through efforts to put over the blanket a thick quilt !!! The other thing is the blanket was claimed to be made from safe material, but it seems to be made from cheap plastic. Upon heating up, it produces very strong chemical smell that really gave me headache. The smell sticks to all my clothes that even would not go away after washing. I sent emails and messages 7 times, not a single response. I just want my money back, this product is a waste of money and time.
