Haven't found a downside to our new 2 Star yet. It's a cooking machine. As for add on's, I think a full size second shelf is number one, if you do any large cooks, or don't like your ribs cooked on edge in a rib rack. I just bolted up the front shelf today, and really like it. Very handy. I went with the blue tooth remote control instead of wi fi, and really like it. Simple and foolproof, and if I were to haul to an event, etc...there's no changes.
