I put the inserts into one of those hot/cold bags (got at the grocery store) and the inserts are still solid when I get off work apx 6 hours later. They also can be recharged in a refrigerator or in ice water, takes about 15 minutes or so. We have had them for about 5 years and couldn't imagine life without it, also use it to do yard work.
