I want to thank the seller for the free shipping to and from my store. We recently made a 20x21 concrete pad for a gazebo. After the build my wife tosses a monkey wrench into the idea by wanting tile on the concrete. We purchased this but once we got it, they did not click together easy, when they did, they looked cheap. The plastic and wood also looked and felt cheap. I do not know where anyone would use this, I would have used it if it was made of high quality materials and looked extremely nice. In the end, we returned it and purchased $800 of tile.
