I was so excited to find this item as I was convinced it would add a lot to my limited pantry space. Well, I can't say how the 18" system holds up, but the 24" setup is way too flimsy. The back braces are PLASTIC (actually 4 separate units for each side that you slip together creating weak joints that pop apart) and unable to hold much weight at all without buckling (ditto for the baskets which change shape too when even a small amount of weight added). Definitely you could not put cans on these as the pictures suggest. Also, wire baskets have wide spaces that will allow smaller items, like spice bottles, to tip over so doesn't work for those as I had hoped. Anyway, if we hadn't drilled the necessary holes in the door to mount this, it would go right back to the vendor. Instead, I will be storing lightweight items like paper towels, crackers, tea boxes, etc. in hopes of getting some use out of it and try to keep that door closed so I don't have to look at the obvious sagging in some places. Hope I have saved someone else this same experience.
