We have not installed this vanity yet however, it has a beautiful look and the quartz top is of a very nice quality.  I took off one star because the wood is not quite as sturdy as I would like.  There is already a small scratch or chip of the black color showing the lighter wood color underneath.  We may have done this when we moved it to another room to store it while we finish the bathroom.  I can see more of these scratches showing up in the future.  It should be an easy fix with a bit of fine grit sandpaper and some black paint.
EDIT: 2023 The quartz top has etched terribly.  I am so sad as this piece was wonderful in my bathroom remodel.  I am not careless with spilling things however it is a bathroom so there is water, hairspray, the occational makeup spills but I never thought the counter would be quite this delicate.
