These are nice. They look really good. Nice metal accents with real wood. These are great. They went together pretty easily too. Anyone could do it. The only complaint I had about these is that I had to predrill the holes because they had not gone deep enough at the factory. They had small dimples where the screws were supposed to go. I had to make them actual holes with my drill. Not too bad though. Other than that they are awesome. You could even lightly sand and paint these to be any color you wanted. The metal brackets would pop right out and could be easily reinstalled after the paint dried. I like them a lot. They might be a bit smaller than I had imagined but they are as advertised. If you line up 3 rolls of TP that’s about exactly how big they are. Hope that helps. Take care.
