Product quality. No where near the quality that I was expecting for the price. I wasn't expecting oak or anything, but found that this product should be sold for no more than $60.00! The wooden dowels were too small and fit very loosely. Some of the pre-drilled holes were too big. Therefore the screws wouldn't not tighten down. I needed to install the screws wet with wood glue. The backer board was supposed to go on  vertically. Too long. Had to install horizontally and the 2 pieces overlapped. I could live with that as it will be against the wall. I bought 2 of these. Would advise whoever is looking to purchase to check out Home Goods. You might find a better product even if you have to pay a little more.
