I bought the same system in 2020 and the newer system I just purchased is not made as well as the older system - the metal on the newer one is thinner, but the overall stability is still good and the appearance  and finish is superior to the other shelving systems purchased in the big box stores. The supplied mallet (solid plastic) is worthless and I suggest using a real mallet that has a wooden handle and a rubber compound head.  Nice product but a tad pricey for the lack of metal thickness.
