I setup an automatic system with 2 & 5 gallon buckets that I use for curing. I cure for about 3 months in those, then I either turn off the air to the bucket and leave it or put it in one of these and they work great. I have a few cvaults too and they work well but they are over priced IMO. The price of metal goes up every day but plastic pretty much stays the same. Freezer bags work great after the cure but getting freezer space from my wife it tough.
