These containers work pretty well and are arguably the best of the ones I've tested/seen so far. For example, the coated wire ones sold at places like Bed, Bath & Beyond were horrible and did not stack at all. These containers actually stack, but they need to be filled with cans to get a proper fit. That's not going to be an issue for most people, but I find it annoying when I empty the top container and it falls into the bottom container that I'm trying to get cans out of. I have to keep both containers full...which defeats the purpose of having stacked containers of the same thing in the pantry.The other small detail that I don't like is that they don't stack squarely. The top one sits just a tad further back then the bottom container. So, they don't fit perfectly on a shelf on other square area.Other than those two things, the containers work very well.
