Bests & Worsts Reviews from Amazon

I have a bunch of the 27-gallon Black & Yellow containers that this is supposed to work with. I purchased these shelves specifically to store those containers, but it turns out that the shelves are about about 1/2" too small to actually fit them - which is, you know, astonishing. The shelves themselves are reasonably easy to assemble and seem reasonably sturdy. But it's just inconceivable to me that a company would design these shelves in such a way that they don't fit the primary containers that they sell. I just don't understand why they didn't make the shelves an inch taller.
