I ordered a hatch cover for my toy hauler. It needed to be the specific size, brand, and style listed in the add to fit. The brand I ordered from Warehouse Deals was Ventline. The product I received was Heng brand. It was 1/2 inch too small to cover my roof vent and the hinge was the wrong design. There was no invoice in the box, nor any return information. I contacted Amazon and was told this was not an Amazon product so I would need to contact the seller. I had no contact infor for Warehouse Deals. I am currently stuck with a product that I cannot use. Ironically, Amazon has contacted me three times to answer potential customers questions about this product. I've told them each time that I received the wrong product, but no followup has been done.
