I really like these doors.  The only issue I had was that the rails are pre-drilled and came with plastic fillers to bolt directly into the sheetrock.  From my experience, hanging an 80lb door on sheetrock is a bad idea.  So I just located the studs and re-drilled the rails so they screw directly into the studs.  I also cut the rails to fit my need since my doors were side by side.  Easy to assemble, easy to install, and they look great.
