Effective Product
I have the NatraCure Universal Warming Wrap (412-CAT) and it is outstanding.  I heat it in the microwave for a minute and a quarter and it stays warm for about 15 to 20 minutes.  I wrap it around the back of my Parkinsonian and arthritic neck and it provides genuine relief from stiffness and discomfort.  In sum, a pleasingly effective product.
