I purchased a couple cases of the black and grey tiles about 6 weeks ago. I installed the floor tiles, liked the appearance and the ease of installation. So, I decided to purchase another 3 cases of the grey and 2 of the black. After attempting to order the grey, I quickly realized that the grey tiles in the 50 and 55 cubic feet boxes were back ordered. So, I installed all of the remaining black tiles on the outside perimeter (walking area) around our vehicles. Well, about a week later, the grey tiles were back in stock and in transit to my house. I finished up the installation of the grey tiles (parking spaces) as soon as the new shipment of tiles arrived. As of now, all of the gray tiles are installed. My last step is cutting and trimming the black tiles to fit up against the walls. The cutting and trimming is by far the most time consuming portion of the tile installation. The final trim and installation of the cut/trim tiles is happening this weekend. I am really impressed with the look and durability of these tiles. I paid about $1.60 per square foot for the tiles while very similar tiles from the name brand manufacturers for about 3 X the cost. I am very happy that I found these tiles and VEVOR.
