The door is top quality, and instrucrions are pretty easy to follow.  You will need a minimum of 2 people to install, as it is heavy.  Im very pleased with fitfinish of the components.  The door glides easy and quiet on track.  The only disappointment is the orientation of the rollers with the way I mounted the doors.  The inside virw of the rollers face outward, and there is no way to fix this.  Other than that, top quality product.
