Well I got my Performer this past Saturday to add to my big Memorial day cookout. When I put it together that saturday night I noticed the lid didn't fit well. I put it on my countertop inside which I know is definatly flat and the lid rocked back and forth. I'd say it was about a 1/4'' gap between the lid and the countertop on the bad sides. I called Weber that night and they said they would ship me out a replacement (great customer service). In the mean time I had already planned on using the performer and she said I could so I did. In order to get cooking temps down a little I had to try and straighten the lid which worked perfect other han the fact that it messed up the coating near the edges. Well today I get the new lid and it has the exact same problem only not as bad but still not what i'd expect. It also seems as if the diameter of the two lids are larger than the base. With the lid on I can slide it back and forth and side to side atleast 3/4''. Nothing like the fit on my WSM. If I push the lid to one direction and look into the top vents I can actually seem daylight around the opposite edge. Am I being to picky? Does anyone have any ideas before I call back CS again? Thanks
