This is one of those gear purchases that you will have forever. I have had my set for at least 8 years and it works just like new.
-Boils taste free water
-Easy to clean if you don't burn anything
Part of being timeless is the loss of a coated finish for non-stick/heat dissapation. For me this isn't an issue. If I burn something like chili it will leave some black on the bottom but at home it comes off with a little soaking and scrubbing.
The handles can get hot if you are cooking something on the fire while your other pot is on the stove. Also when using the top to strain water you have to squeeze the handles on the pan tight or they may buckle into the folded position leaving your food to defy gravity on its own.
