All products manufactured by MossBack Fish Habitat are guaranteed by a Lifetime Warranty against defects in materials and workmanship from the date of purchase. MossBack Fish Habitat will replace or repair (at our discretion) without cost to our customers any item manufactured by MossBack Fish Habitat found to be defective as a result of defective material or workmanship that is still owned by the original purchaser. We will not, however, repair any item which is not properly installed, abused or subject to any use other than that which was originally intended. The warranty does not cover normal wear and tear of the product (including zebra mussels and barnacles) which is expected over the course of ownership.
