Although I really liked the product, I was sold 14 boxes more than I needed for the square footage provided. I had two different installers do the measurements. I explained to Trina KIng the room was a large rectangle, needing few cuts, but this was not factored in the amount I was sold. Of course, they wouldn't take back the unopened boxes. In hindsight, I should have decided the number of boxes to buy instead of letting her order for me. I trusted her. I shouldn't have. The measurements were correct - they should know how much to sell to their customers. 14 BOXES TOO MANY is outrageous. I will never trust them with another project. Beware....
