When they say smokeless they mean it! My goodness I love this thing! Its was rainy, but we still wanted steak on the grill..I will admit I was skeptical about smokeless, but my goodness there was NO SMOKE at all ! It worked so much better than I ever dreamed! The searing of the steaks was beautiful and gave the meat the authentic outside grilled texture and taste. When it was time for clean up, the grate is very non-stick and wipes down nicely. The catch pan, while I thought would be difficult to clean, was actually a breeze to also clean.
