Grill has used more gas in the short time I have used it 4 months) than my old grill would have used in 2 years. Opening behind lid allows so much air to come in that you cannot light it. Too much air comes in around grease shield. Had to make shields for both. User's recommendation: Stay away from the 3 in 1, 5 burner grill. As usage is high. Cuisinart says as long as it isn’t leaking there is nothing they will do.
