    good product
    I ordered 12 rolls for my basement floors. The rolls are not individually wrapped in a plastic bag so they arrived in two cardboard boxes somewhat disheveled which was a concern. I talked to Amy at customer support who assured me that this would not affect the installation. Ultimately we did go ahead and use the underlayment with little difficulty and were very satisfied with the quality and price. Amy even refunded us $25.
