Easy to assemble. Looks fine. But in Q&A section of website says a grill mat will be fine under this but the instructions are very clear that you need something far more substantial, i.e., bricks, pavers, etc. When using it on a deck. Also got a steel splinter when assembling. Edges are not perfectly smooth. None of this is insurmountable. I have bricks, I got the splinter out, but there were these problems.
