I've been fighting with the deep inside blind corner of my kitchen cabinet for years (even with doors that open on both sides of the peninsula). I finally decided that this would be the best solution for the items that keep getting lost into the no man's land of the corner cabinet. This installed easily and quickly over a couple of hours. I used both the paper installation instructions and the rev a shelf you tube video for the product for reference. This organizer doesn't occupy the entire cupboard, so I even had room to insert a narrow shelf to hold kitchen items that I don't use all the time.
