This is a really handy thing to have in your cupboard but you have to have the right size things to put inside.  I removed a shelf so I'm using only 3 shelves, and some of my items are still too tall to fit inside.  I've filled it with baking supplies and spices and I love how it keeps things handy.  The installation on this thing is tricky though.

Pros: good value, functional
Cons: tricky install and tricky to fit things inside
