The product itself is fine, it did take quite a bit of tinkering to get everything to line up. My husband is very handy, so he was able to figure it out. I could see where the average person would have issues though. I would have given five stars for this product, but I docked 2 stars for the professional installation I paid for. The tech only work for an hour and a half, and then lied to me and said that Wayfair only paid him for an hour and a half, if he were to stay and finish the project, they would charge us $50 an hour for his overtime. Come to find out that was a total lie. So we were left with more of half of the project undone that we had to do ourselves. Even though we paid for a professional installation. Wayfair/Angi would not offer a full refund. Very unsatisfied with that portion. I would not recommend using a professional insulation for a product of this size.
