The one concern is Baby Back Maniac developed a leak in the SS gasket and Weber's ultimate response was "working as intended."
That's the initial response he got. He actually ended up getting a follow up call from the President of Weber. The replaced the hinge on his Summit and it works like a charm again. Anyone with that issue can contact customer service and they will do the same, free of charge.
I've had mine about 6 months and it is by far the best grill I've ever owned. one of my first cooks on the Summit was an 18lb packer when it was about 12 degrees and spitting snow outside. Held 250 for over 12 hours with only one vent adjustment and i had coals left over when it was done.
Temperature control really is amazing. I can sear off ribeyes at highest heat possible, shut off the vents and its cool enough to cover or wheel back in the garage within an hour.
