I would rather not, but "have GrillGrates, will travel"
They help a lot setting out temps on a lot of cheap gassers! But will only do it if asked to. I'd be kind of put off if someone wanted to take over at my grill, so wouldn't do it to anyone else
We did a tailgate at a Buffett concert last year before I started chemo. Using a cheap CharBroil mini event grill (with the GrillGrates), had a friend remark it was the most even heating grill he'd ever seen!
