there were several really good reviews as well
I had to rewrite this review because the seller pointed out that I was quoting reviews from a similar product.  I was looking at two products like this but actually clicked on this one because the other had too many negative reviews.  However, like the other product, this one only holds the heat for a few more minutes that the one for $9.99,  They are really nice for about five to eight minutes.  Then they become quite cool.  I am sorry that I bought them. I would have expected at least 15 minutes of nice heat.  The small microwaveable pads (not foot shaped) that we use hold a nice heat for about 20 minutes.  Thus, I only expected a slight degradation in that capacity from this product.  The materials they are made of are indeed quite nice; however, the heating material inside is not as nice as other products we have that hold the heat.  Caveat emptor!!!
