I can't remember how long ago I bought the equivalent model and am finally looking to buy the same unit. The Favour Wave dispersion system helps to considerable reduce, but not eliminate flaming. It is better than other propane barbecues I have used in the past. The cover has not warpeed, even though I have had a few sessions where I forgot about it and the temperature went way up. The biggest knock is the cast iron grill. It rusts over time. I think I am on my third set.  My unit has been reliable - and still is actually - but I am upgrading for use at home and taking the old one to the cottage where I expect years more use.
