I've had this BBQ for a month now and I really love it. It came mostly put together, the firebox came completely assembled with the burners and rear rotisserie burner installed. This beast has tons heat when on full blast. I've easily had the grill temp (measured at the grill grates) up to 750f ! No wonder the directions say to not leave it on high for more than 10 minutes to warm up. When the burners are on low it can easily cook something delicate like marinated chicken. The BBQ is easy to clean. All the internal parts can be removed to get good access for scraping out any gunk in the bottom. The heavy duty parts, stainless steel firebox with aluminium end caps, and overall well built unit give me the impression that it will last for years. Don't forget that the regal and imperial lines have the same firebox, and that they have lifetime warranty on the firebox and all aluminum parts.
