The heft of this storage rack exudes quality.  Solid construction and compact.   No assembly required. Take out of the box, position the rack, and start loading your CDs.   Not for boxed sets, DVDs, or VHS tapes because the shelves are not adjustable but perfectly sized for CDs in jewel cases.  Won't ever have to worry about the shelves bowing.  Not inexpensive but you'll be getting what you pay for; will last a lifetime.   

Pros: No assembly required.  Solid construction.
Cons: Pricey.  Shelves not adjustable.
