Barn Door Bar/Rollers well made, very poor instructions on how to setup for proper installation, first barn door I have installed but I would consider hanging a pre-hung door easier, if not for YouTube & helpful hits would have been a nightmare. I would also recommend it states hang wood ledger board and even better come with one in kit, without ledger board adjustments again would have been nightmare.  Door quality ok for price, some rough/questionable areas, hanger pre-drilled holes need better alignment, again installation instruction need improvement. mm to inches would be nice on instructions. A person with limited skills and lack of assortment of tools, would struggle through project, that was the only thing that saved may installation.  All that said, end results Good for the price.
