We installed Karastan Barrocco Mineral #78008 made from SmartStrand in 2015. Within a year the traffic pattern was a disaster. We are 2 adults living in a 4000 ft pristine home, cleaned by a housekeeper. Karastan Inspector came out and said we would have to hire a lawyer to proceed with a claim. $4150 original cost including upgraded pad. Ed's Fine floors in North Richland Hills, TX were great to work with and agreed the carpet had worn very badly. Now I am replacing with Nylon which has worn well for us in the past. I bought Karastan due to quality image, but never again and never again for SmartStrand. I am attaching the most recent picture. Buyer Beware!
