I agree with many of the other reviews - backing is rather flimsy (the box it came in was heavier than the backing), where to tack the backing should have been outlined on the backing (this caused many nails to come through the board or not fulling into the supports). It was fairly easy to put together and overall looks very nice one final.  The wall zip tie could have been a little longer but I was able to make it work.  It fit our needs very well and still has plenty of space for us to expand.  I would purchase it again -just wish it was a little better quality (mainly the back piece).
