The unit was made in China (where else?) and came with assembly instructions that were, at best, elliptical. (On the other hand, more hardware than I actually needed was provided, including some items that seemed of no use whatsoever.) The lack of critical details led to some assembly and dis-assembly, but, in the end, I had the sort of wine rack I was looking for. In case I go on a wine buying spree, I can even stack another rack atop this one.
Pictures of my new wine rack are below.
