The only thing I don't like about this item is that I didn't buy it years ago! Seriously, though it is so helpful to actually see what is in the back of the cupboard and I think it is really going to reduce the number of snacks and such that sit in there until way past their best before. Set up was easy and straightforward. It says there are three sizes possible but there are really more like 6 because the two sides each slide into 3 possible positions and you can mix and match. The sticky tape for installing is not really strong enough for this application but it will do if your not handy and can be careful when pulling out the drawer. Overall, I love and recommend this purchase.
