The manufacture of these cabinets are of dubious quality.  Three out of four had serious manufacturing problems.  Joss and Main stood behind the products and offered replacements and/or refund of purchase.  These products were found to be made in China.  I was able to scavenge parts to repair two of the cabinets so they were usable.  Joss and Main is an excellent company to work with, but one has to be careful what is purchased.
