be interesting to see if yours is sturdy enough- it doesn't actually describe itself as a fire pit though- just says it has a firebowl which all BBQ's have don't they? Probably I'm wrong.
Our's started to Buckle after a short time as well , i think the stainless metal is not thick enough for the heat , and after a time it just starts to deteriorate .
