The instructions were easy to follow, I outlined all measurements, prepped the cabinet and the next day we finished the install.  It was a nice tight fit, all pieces were used, which is always a good thing.  Somehow I always end up with extra screws.  The only hang up was that when I looked down the inside of the wall I noticed we had electrical running right through where my outline was.  So we adjusted the cabinet and moved it a little higher to not interrupt the electric.  Its higher that the instructions but it still works.  Just beware of possible wires once you open the wall up.  You will notice in the picture the original line was marked.

Pros: Easy to assemble
