Heavy gauge steel construction, especially the legs when compared to others on the market.  Nice looking retro look.  Assembly was easy.  Many complaints on the web about lining up the legs with the bottom shelf, but that can easily be remedied.  Attach the legs to the bottom of the cooler, as described in step one, but don't tighten the bolts all the way.  That will allow some wiggle room for the bottom shelf alignment.  Once all bolts are in place, tighten them.  My only complaint is that the insulation looks a little thin.  Have not tried this yet, so I can't tell how well the insulation works on a hot day.
