I give these each year to the thoughtful people who help kids disembark from their parent's cars on school mornings. The product arrived in a few days -- great service !!
The hand warmers were a gift for a co-worker. She mentioned needing them because they really help treat the arthritis in her hands. So, I'm sure anyone who suffers with arthritis might want to try these even if it's not a permanent cure it does make life more comfortable.
