I scored one of these this weekend to give it a try; just something to use on my gas grill until I can get an actual smoker.
I'll be damned....the thing worked outstanding on a big batch of wings did yesterday.
puts out a TON of smoke. Up until this point, I had tried a smoker box thing, and even some pouches made out of foil with wood chips inside. They worked 'ok', but didn't last very long at all.
I filled the tube up with pellets, and the damn thing smoked like a truck stop waitress for 2 hours, and still had about 1/4 of pellets to go. Supposedly the 12" tube will last for about 4 hours; I think that's probably pretty accurate based on what I saw. I probably let the initial flame go a little longer than necessary and burned up more pellets before blowing out the flame.
I would say that anyone with a gas grill that wants to cook anything at that 250-300 range for an extended period of time, should check it out. I suspect it would work great with anything with a sub 3 hour smoke. Don't think I'd try a brisket or anything, but wings, chicken, ribs etc would be good. Might try ribs next weekend and see how that goes.
Granted, a smoker will always yield better results, but I was super pleased with it the first go around on the gas grill. wings turned out great, though I think my thermometer on the grill is off by probably 30 degrees or so. I had it going at 300 indicated on a single burner about 1/2 way 'on' for 45 minutes, then another 35 minutes after turning the wings, but the skin was still a little rubbery. Not super rubbery, but a little more so than I care for. next time I'll probably do the smoke, the at the end apply some direct heat at the very end to see if that will crisp up the skin a tad.
