We have a small powder room that previously had an inward opening door.  I used this barn door to replace that inward opening one, and have gained a nice bit of space as a result!  I've never installed a barn door before, so this did take me a while (I'm ashamed to admit how many hours!).  Part of that time was used in attempting to secure the backer board.  I found that the screws provided to secure it to the wall were inadequate; they bent while I was trying to drive them into the studs and I had to replace them with better quality screws of my own.  Other than that, though, everything provided worked well and the end result looks very nice.
