The warranty we off on our Nitro Tiles is a manufacturer's defect warranty, which only covers issues that would arise from the manufacturing of the product. These issues typically pop-up right when you get the product, but sometimes certain issues can take some time to arise. We offer a three-year warranty to cover this fact. Some manufacturing issues take a while to arise, and thus, want to make sure our customers know they can come to us. If something were to arise after the three years, customers can still reach out to us for assistance via email, phone, or chat.
