They used LAG Screws at the hing  points.  The holes quickly wallowed out causing the legs to wobble, COLLAPSE and fail.  I went to Lowes and had to purchase 4 X flat head furniture bolts to cure this fundamental flaw.  Once I replaced the lag screws with the furniture bolts we had a nice sturdy portable table.
Wood quality, stain work was very good but use of lag screws was huge mistake.
