I ordered both Base and Signature Modin plank samples. The Signature is much thicker than Base and feels softer under bare feet. All of the samples looked very woodlike. An installer bidding on my project was especially impressed with the Signature sample's 40 mil wear layer and Lifetime Residential Warranty. He said that none of his top brand products even came close to that quality. In addition, he didn't know that a 40 mil wear layer was even available to residential consumers. Then he asked me about the cost. When I told him $4.50 per sq. ft., he replied that I should get it; but not to tell his company that he told me to buy a competitor's product. A dustless tile removal company representative also was equally impressed with this product. These were two different gentlemen from two different companies who came to my home on different days. I plan to use the Elmstead Signature for my project.
