Review on Gray Interlocking Rubber Tiles: 50 PCS, 12x12x0.5 Inches, Drainage, Outdoor Deck Flooring for Pool Shower Bathroom Patio Garage by Noah Warneking

Easy to use, easy to assemble. Rather than laying them face down on the floor and trying to assemble them, I assembled them from the back by placing the loops over the clips, forming a "V," then straightening the panels. To unlock, quickly join the 2 outside edges into a "V" and the panel will separate. The only problem is that I only had 49 records instead of 50. The seller responded quickly and fixed the problem with the missing part. Tile is great for basement placement as it allows air and water to pass underneath.
