I have one of the renate pieces, and FYI- I HATE, HATE, HATE it. It wobbles, the finish is ugly and fake (the wood veneer is blotchy and flaky, and the metal parts are lumpy and black/fake rust colored and splootchy), and the wheels don't work.
Wow! Thanks for the feedback, so good to know. Too bad the quality is so iffy, they're such a good alternative :\
