I haven't personally used Quick Fix. But, the reviews of it on here are amazing. I have yet to hear tale of someone saying that they had problems with it. As far as heating goes, it not only comes with a heater, but a temperature gauge, I'm pretty sure. Since it can be re-heated over and over again without problems, you might want to order some extra heaters for it (or pick up some hand warmers) and experiment on your own as to what works the best.
