only flaw is that its prone to subtle mis-assembly (screen before and below 4 firebox perimeter L-pieces, rather than after and inside them).

this happened on 2nd nite of use; overzealous fellow camper didnt have explicit instructions and blundered,
and shield was too close to screen & fire, and was destroyed.

Once you show it off, guard against its misuse by your friends, or it will happen to you too.
