The Chefman Indoor Grill produces less smoke than traditional indoor grills, so you can enjoy perfectly grilled food year-round without having to stand in the cold. To achieve that perfectly smoke-free grilling indoors, the drip tray must be filled with water between the minimum and maximum line. The water instantly cools the grease that falls on it, preventing it from sticking to the tray or from smoking. With an extra-large 15" inch cooking surface, you can cook multiple foods at the same time for a complete meal. It also features a cool-touch handle and overheat auto shut-off protection for added safety.
