Shipped quickly. Pretty damaged corner upon opening. Must have been hit hard as this steel does not bend easily. The bend makes it basically unable to accommodate stones/bricks around underneath as it isn’t flush. Other edges also don’t line up great. 
Also seems like a somewhat poor design with a steel rod underneath at the edges which makes it so stones would not be able to sit very far in underneath.
I wouldn’t buy it again. If I can contact the seller to send me one side to replace this damaged one I’ll update this review.
