Title: works for headaches but lasts short period of time and takes forever to microwave
Review: As the title says, it does what it's supposed to do.BUT it keeps the temperature for only a bit more than an hour, and takes a long time to refreeze.Microwaving it (in case you need the warm one) is a hassle: it takes too much time (>10 min) and even then heats very unevenly.
