Most of the assembly was easy but there are glaring QC issues that need to be addressed. One of the bottom rack retention screws did not line up with the welded on nut and subsequently will not tighten, one of the pegs on that the griddle surface sits on and locks into the cart was welded on at almost a 30 degree angle. Other than those issues the blackstone products are great, just disappointing to the some issues slip through the cracks
