I would have liked better installation instructions to be included with the product.  I happen to be quite handy, so I was able to install it with little trouble, but I can easily see how a person who may not be all that handy, having quite a bit of  trouble installing this unit, let alone not aligning the holes to match on the wall.  I would strongly suggest a template to tape to the wall so the installer would be able to level the unit and drill the holes perfectly in the wall to match the pilot holes on the unit.  If I had not made my own template to ensure a correct installation, I would have required a second person to help me.   A template would have made the installation very simple to perform.   The pilot holes were hardly noticeable and the suggestion to use a 3/16" drill bit for the plugs supplied with the unit is incorrect.  5/16" is the correct drill bit size necessary for the plugs supplied.  
The unit is very nicely finished and looks great in our bathroom.
