Loved the bigger samples of Marmoleum, helped me decide to order. Quick turnaround on the quote and ease of ordering were plusses. My flooring was delivered, as scheduled, on carefully wrapped pallet, delivered by a very polite and helpful delivery person. Can't wait to have my new floor installed!

Not as described. They put bubble wrap radiant barrier around some rockwool on the top. Not as described. The images are different than what I was shipped.

Reply from Eco-BuildingProducts.Com

Jared, Thanks for your feedback and review. The product page contains a wealth of information, including a relatively well-written description, dimensions, and images. I agree that our product description doesn't resemble your description. The recessed light cover is a cone-like cylinder measuring 14" in diameter at the base, 12" in diameter at the top, and 11.5" in height, made with TempSheild's Class A/Class1 Single Double Bubble Foil wrapped with a rockwool insulation top. The product page features two images, both of which accurately represent what is boxed and shipped. If you feel misled and unsatisfied with your purchase and the item you received, you are welcome to return it for a full refund. Let us know. Thanks
