It’s the expected high quality materials from Kamado Joe.  As a rookie pizza griller, I find it difficult to manage the pizza in the narrow opening, which was made easier when I got a peel that actually fit (as opposed to the one they sell).  My only other issue is that it’s a bit difficult to get the heat deflectors in and out.  But my pizzas have turned out good, despite my issues loading/unloading the grill.  Any issues are largely my lack of experience and not the DoJoe.
