I like my glass jars. Each one has been used at least 30 times. Worst case, I have to buy some more lids. Never broke one.
Huh... learned something new, I would have thought the jars would crack when the chili froze and expanded. I make batches of chili and then vacuum sealer bag it. I cut the bags large enough so even when filled they're kind of flat and lay in the freezer nice. They actually work out nice and can be used as as a freezer pack of sorts, when I pack food in a cooler for a weekend trip.
