The product looks exactly as it does in the photos, and the current price on Amazon matches the lowest price I've seen at large chain home stores. I saw it for nearly 2x's the price at a smaller garden center!
The installation is very easy, but you will need a drill for attaching the brackets to the boards. The composite timbers are plastic-looking, but an attractive reddish-brown color. Everything seems solid. The stacking feature works very well, not wobbly or loose-feeling.
The one drawback is that about the only thing you can do with this specific kit is make the 4x4' square. If you need more flexibility in your design, the company does sell just the brackets, and you could cut your own 2x6 decking to make larger areas, different shapes, etc. and save a little money.
