The bullets are great to begin with, and if you do not lan on cooking massive amounts of Cue, it should suit you well. As Bretto said, the metal housing is thin, and does not retain the heat, especially in colder and wet weather. However, the wind break he descibed helps. I've never used the blanket, just added more time, and in essence more coals. The paint job will eventually wear off, dull, and get blackened. The cover will warp a bit because it is thin metal as well. IT has two cooking levels that can acoomodate a decent amount of poundage. I find it hard to do a rack of ribs, unless they are coiled, or you can cut the rack in half. A shoulder fits easily, as does a medium sized brisket. Plenty of room for sausage, wings, and chicken. Whole hog...I don't think so.
The best advice I can give you, if you purchase one, is to wrap the water pan ENTIRELY, several times with heavy duty aluminum foil. This will cut down on your clean up time tremendously. And, you can fill the pan with either water or sand. It is merely to maintain an even cook temp. The water does add moisture, but the results are similar. I prefer water, it's just easier to deal with, IMO. Good luck in your decision.
