I bought two of the 12" models to replace my cheap Chinese keyboard drawers that were in my built-in computer desk. They are much better built - thicker/harder metal, solid construction, good end bumper and the bearings run smooth and quiet.The rails also 'click' quietly with a slight 'pop' when you slide them all the way back and prevent that the drawer pops out unintentionally when the cabinet is not perfectly level etc. I am 100% satisfied with the quality and price and would definitely recommend them.
