Let me start by saying that I'm totally aware of how stupid I was in not considering this. In hind sight, it was obvious, but I still made a big mistake based on the instructions that were included.
There is a large magnet on the back of the receiver. It instructs you to use that to mount it to the side of your grill. If you have a gas grill, this probably works perfectly because you have a cabinet for your propane tank. I have a pellet grill, so there's no cabinet.
Like an idiot, I attached it to the side of the drum. You can imagine what happened when cooking a whole chicken at 425 degrees. The whole back of it melted.
Now, as a shout out to the quality of this product, even exposed to that heat and with parts melted, it still works perfectly. I just have to rest it on a little table next to the grill and explain my stupidity to friends when they come for cook outs.
In short, I recommend the product. It's great. Just don't be dumb like me.
