I love this flooring. For almost two years I have had 2 crazy-wild dogs scrapping around on it and teens riding skateboards on it and it still looks brand NEW. The seams are so tight that the few water spills I've had on it have not gotten through to cause any swelling. The spills were from overwatering a floor plant and the water sat at least over night.
Again, a great product and I installed myself. ^-^ Incidentally, I would NOT allow the aforementioned chaos if the floor couldn't handle it like it does. Amazing!
