I have a deep kitchen pantry and I had been trying to figure out how to best use the space. My shelves are 19" deep and we used to fill them to the back, then forget what was back there and purchase the same items again. On top of all the double purchasing, it was just a nightmare to keep organized. I knew that turntables would be a great help, but I worried that these would be too flimsy to hold all my heavy cans, jars, bottles, etc. However, because Copco offers the large 18" size I needed at a reasonable price, I decided to take a chance. Turns out they can hold as much as I need and still turn easily. I loaded up one with jars of spaghetti sauce, oils, vinegars, etc. The second I filled with large cans and glass jars full of grains. No issues. Even when loaded unevenly they still turn with ease. I can't speak to durability yet, but I'll update if I have any issues. For now they've brought so much more functionality to my pantry. Everything is easily accessible and it's almost as though they created more space. I did not purchase these from Amazon and one turntable arrived warped, but it did not affect functionality once loaded with items. Highly recommended.
