I had purchased 5 of these roll out shelves and installed them last year.  They are absolutely amazing in every way.  From the craftsmanship to the ease which they roll regardless of how much weight is on them.  I just purchased my last one  to hold my stand mixer, food processor and blender.  They are so smooth to slide out and are well made.  I would recommend these to any one who wants to make accessing items with ease!!!
