My entire lower and one top kitchen cabinets have been refitted with  metal Rev-a-Shelf, and I love all of them. But a great example of their usage is, we installed one self under the kitchen sink, which is always a mess - guess what, only one and everything that was under the sink is now organized and easy to get to. I love these products. I'm now waiting for the helper to have time to install the second shelf under the kitchen sink and I have shelves for both bathrooms.
