One of the few things I have bought that I did not read reviews of. I was looking at them a moment ago too. I see the 2 most recent complaints about warping came from folks that look like they were using it on outdoor grills. Not sure if using it indoors on a range will make a difference or not. I see that many of the warp issues in 2019 were from units with no bracing. I see one of the most recent warp review was the 18 x 18. I am going to assume that the most recent warp review of the 32 x 18 had the cross bars, but I do not under stand why you would put the unit in a gas grill what I would consider backwards. You have the grease tray area at the back and the high sided backing in the front. To me that makes no sense. To under stand what I am saying, imagine I turned the grill 180° from how it sits in the 1st photo, and put it in my gas grill. I just don't get why you would do that.
As far as a review, I will just post my cooks on it over the next few days in here and then maybe just move it to the Review section. No moving parts, no knobs, pretty simple. I guess it warps or it does not, I think we will all be curious to see how that goes, as it says it can take 600°, and I will probably push it to those limits. I think I will have pretty good control on the range, the guys putting it in their gas BBQ and probably walking away...I wonder how hot those get, with 4 burners going?
