OK unit, but could be better.  Here are the few issues we faced.
The pre cut opening planned for the pipes was too small. We had to cut the unit in two places. First cut was to extend the existing opening downwards by couple inches, and the second one was on the wall separating the drawers from the rest of the open storage space.  I will upload a picture to show you. Pretty disappointed considering the cost of this unit.  
The back splash was also not a simple job.  We had to remove our baseboard in the back so the unit will be sitting more flush to the wall. This tore quite a bit of the wall and created additional work that was not anticipated. 
Lastly be sure to read on the exact measurements on the back. I wanted the vanity to be another 4-5 inches to the left, but this was not possible as the existing opening could only be extended one way due to the drawers being on the other side.
