Metal insert is very flimsy.  Can't imagine burning any wood in it that would last more than a few minutes.  It is also very shallow, only about 6" deep.  This does not rest flush in the opening and the top screen guard does is not rest square.  The outside "stone" looks good. Right now we will try and make the best of it.

Pros: Natural faux stone
Cons: Insert will not last a season and is very limiting as to usage.
