I have room for two under a bathroom vanity so I ordered one new and one "returned" based on positive experience I have had at other retailers.  The new one arrived in about a week, installed easily and works perfectly.  The slides are horizontal and flat so might bind under real heavy loading but are perfect for my application.  The "returned" set arrived but only two of the seven parts were in the box.  Wayfair was polite and apologetic, and sent another package which arrived about a week later.  It contained three more parts but was still missing the two parts required to stack the baskets.  Again Wayfair was apologetic and has promised the missing parts.  It's been a week + and I'm waiting.  The pull out drawer I received is great.  The returned item at a modest price reduction, not so much.
