I have not had these for very long, but so far so good.  They were purchased in hopes that they would warm up my hands and help with arthritis because rolling up a heating pad and trying to keep it in place is a pain.  These are well worth the $20.  Here is how I use them:  because they are intended for manicurists they have a plastic liner.  The liner can get hot so I wear a pair of thin cotton gloves and then slip them on.  The warmth is such a relief for cold fingers, which only makes arthritis pain worse.  I am happy to recommend these.
