After researching for the solution for our awkward corner cabinet storage for a very long time, I decided to go with this one, main reason being, this model fits our narrow door size but still has a generous storage capacity, unlike some other similar products (including Lazy Susan styles) that compromise storage space for a smaller cabinet door. Plus it’s A LOT cheaper. I was a bit skeptical in terms is the quality and installing complexity. But it all turned out to be great. Installing is super easy, and the shelves are very sturdy and they roll in and out left and right super smoothly. I’m so glad we went with this product and now no more “black hole” at the corner but only easy accessible ample storage.Also as shown in the last pic, there is this shelf-like part that came with everything else. We’re not entirely sure where it fits and what it’s supposed to do. Nothing is mentioned in the manual or in the Amazon listing info. So if anyone has a better idea, we’d love to know :)
