Shelves are well made for the price, but wish they had dove-tail corners and a thicker bottom.  Decent finish job and good quality sliding hardware.  Installation was fairly easy (took more time to unload the stuff from the cabinet than to install the shelf), but had to shim the tracks on bottom unit would so it clear the small lip of the cabinet frame above the cabinet bottom shelf.   Installation template is a huge help!  

Very pleased with quick delivery.  (Told to expect 10 weeks and they came in less than 3).  Would recommend for anyone looking for a cost effective roll-out shelf solution.
