It is pretty rare for me to write a more negative review, but in this case, here we go.
When I first bought this and received it, I thought it was great initially. It was nice, soft and smelled great. I was very careful to heat it according to directions and it got burnt. I am open to that being me and user error, except for the fact that I've owned quite a few of these types of products and my neck warmers usually never get burned to where it smokes out of the microwave.
So, NO, I don't recommend this. It was a waste of money.
