I purchased approx $5,000 of wood flooring called 'Invincible Titanium Series' made by Armstrong. The product was supplied with such large color variations (quality) that the installer rejected it, and have been fighting for refund for 5 mo. Neither retailer nor manufacturer were supportive or responsive, and would only take back the unopened boxes with a hefty 35% restocking charge. Be aware, the product sample boards are not what U get. The product guarantee is not worth the paper. It was costly well beyond the flooring.
