Cons: 
The upper grate seems like an after thought, its pretty useless and just plain flimsy. 
also there are infarct some hot spots on the grill, mainly closer to the back panel, not insane but prominent enough to likely get worse of over time. 

Pros:
It gets hot, fast, and steaks love this cast iron wavy grate... especially since i cook 3-4in. thick steaks on this thing. 
so far seems to be pretty gas efficient, but I'm still a trainee on Gas grills (need a quick fix vs charcoal).
the build quality is very good, the catch, the whole thing, i love it though its made in PRC (cmon Napoleon)
