Worst flooring I've ever installed. Put down 3/8 solid Brazillian Cherry over concrete floor purchased at Lumber Liquidators. Took 4 weeks to lay 800 sq ft. The adhesive Liquidators sold takes 3-4 hours to somewhat cure but the stuff allows floor movement for much longer. Could only lay 12" of flooring at one time that had to be secured with blocks fastened to floor with concrete nails and had to wait 12 hours before moving on. The flooring itself is junk, lots of poor layers of finish. They say 8 layers of finish but you really wonder how much coating is on the floor considering all the bad spots. And getting the tongue and grove to fit properly was a challenge also. The floor scratches easily and the 100 year warrenty is trash. Lumber Liquidators and Bellawood always say problems are due to installation. Lumber Liquidators doesn't have installation contractors. Want to see customer reviews? Just google bellawood customer reviews. There are 100s of complaints against both companies.
