It is even better than I expected after I read a lot of reviews from this particular product AND from this type of porduct. It really warms up the bed, and it does it only in about 5 minutes. It is extremely comfortable. The dual thermostat is the best since I need only a little bit of extra warmth and my husband likes it really hot!! Very easy to install and it doesn't even show under the sheets. I would DEFINITELY recommend this product!!
