These are perfect for converting an old concrete patio to a new deck area. Installation was very easy, but I don't suggest leaving it up to a child as errors in putting them down, like wrong orientation, are easy to make and hard to fix later. They do come apart again but not as easy as you'd think.. and may break the plastic support frame. Also some of the tiles had the composite deck top slightly offset on the frame which resulted in a larger tile to tile space. I held those tiles for last and used them where I needed to cut. I also find that the ends of the composite deck slats are sharp. It would have to nice for the ends to have been slightly beveled like the slat sides are. All in all a very good product.
