• Lower Wattage: At 825W, it cooks slower than the FG551, especially for searing.
• Preheat Time: Takes 3-5 minutes, which can feel sluggish for quick meals.

Real-World Testing

After six months of regular use, the DG551 has transformed my weeknight cooking. I grilled a 12-oz ribeye to medium-rare perfection using the Smart Thermometer, achieving deep grill marks and a smoky flavor that rivaled my outdoor Weber. The air fry mode delivered crispy chicken wings with minimal oil, while the dehydrate function made apple chips for my kids. The smoke control system kept my apartment kitchen odor-free, even during high-heat searing. Cleanup was effortless—just pop the grate and basket in the dishwasher. My only issue is its size, requiring storage in a cupboard in my small kitchen.
