Review on Maximize Pantry Efficiency with Auledio Stackable Beverage Can Dispenser Rack – Black (2 Pack) by Shelley Highter

I really like these. I bought a test kit and have started buying now when they come in stock. You need deep shelves, but it's not as bad as the dimensions say. The protrusions used for leveling when laying can also be used as legs. They're exactly 13 inches from the back, so if your shelf is deeper than 13 inches, you should be fine. I end up putting them on one of my wire shelves, which also seems to work, mostly because I can adjust the height of the shelf and work even more efficiently. Oh, and they come with spare hardware. One complaint was that I had a box that was missing the back, which is marked "side rails" in the instructions. I consider this an oversight more than anything for a Monday morning worker because everything was perfectly sealed and shrink-wrapped. If you come across this and don't want to worry about returning it, you can do what I did and use the wire to make it work (photo). I could return it but it doesn't really matter and I really wish they were installed.
