I've had a Weber Genesis Gas Grill for some time now and I'm quite happy with it. However, there is one thing you will never get on a gas grill that you get when cook over charcoal - that great smokey taste. Viewed this in Amazon a couple of times and decided to try it out. Not much to say, except that it works as advertised. Fit right in-between the V-bars of my Weber, no problem. It puts out a tremendous amount of smoke once it gets going. I was really surprised how much of a smokey flavor it imparts to what you're cooking. Just follow the instructions and you're all set.
