Perfectly ok. I bought two and design of both the rails and the base plates were slightly different. No problem for my application but could be if you’re having them side by side. Fixings were rubbish but they generally are. Could be frustrating if you’re trying to fit them with what is provided, and you’ll need to buy something better in addition.Uprights and bases felt a bit flimsy but rail was very solid and for the price I think you’ll struggle to find anything that’s a huge improvement. Once assembled with decent fixings they’re very solid.
