[QUOTE=BikingZombie;18354683]I tried an Element Thermos a while back. It worked great, but the steel, or the coating, had some reaction with some of the chicken soup/stews we made and would go rancid by the time lunch came around. Seriously, take food out of fridge, scoop into thermos, bike to work, put container in fridge, open container at lunch and discover the rancid food. This wasn't a single occurrence, this was proven over multiple times with different stews. Weird.

That is weird. The Stanley had a stainless steel liner. I never had that problem.
