Two were purchased for under the stove, where there was a lot vertical space. I can now see the lids that go with certain sized pots. I was able organize my pans and pans, and no longer have to worry about finding the right lid for certain meals. It took some time to make sure you had the brackets in the correct direction. But once you did, everything was easy and quickly worked. It was easy to install. If you enjoy organization like me, I highly recommend it.
