We have not installed the vanity yet but we have taken it out and inspected it.  

The good: 
The unit looks nice on the surface.  
The marble top is a lovely, solid slab of marble with a nice shine and grey vein (close-up photo attached).
The dovetail drawers are well put together.
It looks really nice. 

The bad: 
The doors do not lie flush.  One protrudes a few centimeters and one is slightly recessed. 
There are uneven gaps between the drawers (close-up photo attached)
The divider between the two drawers appears to be separating slightly from the base.
There are also some slight imperfections in the paint.  

Overall, this is a heavy and sturdy vanity and for the price it is not a bad value.  I am hopeful that my handyman can make some adjustments to get the drawers and doors to line up properly.
