The Otzi Ember Flat Pack Grill - Portable grills warping??

[Grady]

I've gone through a couple portable grills and the problem with these is that after a 2-3 good uses, and warm fires, things start to warp all to hell. I'm going to give this one more shot and was looking at this one: https://www.otzigear.com/products/otzi-ember-portable-2-camper-grill-stainless-steel Would you happen to have experience with this grill, or know of it?

Let me know what you think of it and if you would recommend it? Thank you so much!!
