This item made mostly-unusable space in our cabinet usable. It was not at all easy to install and I had to do it several times because the instructions were not that useful. I eventually got the spacing right but it was more time-consuming than I expected. In the end it was worth it. No more digging deep in the back of a corner cabinet when I can put items on these shelves. This is not a perfect solution to the problem but it is very useful and we're happy to have it.
