I love my new end tables.  I got black.  The drawers slide smoothly, but they don't have roller runners.  They come pre-assembled.  Mine were well packaged, but one had a nick in it so Wayfair sent a replacement.  I am becoming a major Wayfair customer.  I hope they will last about 5-10 years, and that's what I think they will do.  Probably easy to beat them up, but they look super nice now.
