I love my slide out shelves! They work just as expected, seem to be well-made and I expect will be a part of my kitchen for many years. 
Installation was pretty easy and quick EXCEPT we received the wrong size template for two shelves (of the same size) which required a lot of fiddling around and making of new templates. One of the shelves is still not installed perfectly due to this but it works decently. Still 5 stars for the actual shelves.
