Used this Grill/stove for 3 days 3 times a day cooking for 4 adults and 4 kids. Instant start, extremely fast. 
If you use it as it was supposed to be used (not putting pans or pots on the grill) you will have no problem with it. I saw the melted grill pictures from the reviews and think it’s only wrongly use of the grill. 
Has fine gas adjustments that allows you just to keep the coffee warm if you want. 
Used 2 small gas tanks (1 lb) in this 3 days for all that cooking. 
I recommend it with confidence.
