No replacement trays or baskets available. Basket is inexpensively made and may need replacement at some point. Manual recommends inside top be cleaned after use. Delicate sheet metal fan could be damaged. Otherwise fantastic product for the price. Chicken wings/drumsticks, fries,  salmon fillets, and reheating pizza so far can't be beat. The unit exhausts out the back so placement needs some thought. Cord too short to move under the hood for smokey stuff. Well thought out product.
