We bought one of these last year. Nice thing about it is that you can smoke without adding any heat. We have a Traeger pellet grill, but although it does well it didn't give me enough smoke for my liking. With this you can cold smoke, so cheese is now also in the running. Fish turns out amazing. Caution though, in order to best best effective your grill needs to be blocked at the top, so the upper vent needs to be below the grill itself, or you will have to block it off with some tinfoil.
