The Masterbuilt 30" was my first smoker and it definitely did its job, but I had trouble getting as much of smoke flavor and color into the meat. And from other folks that have used the smoker it seems as though it is just this way across the board. I used about every combination of wood chips, wet wood chips, dry & wet wood chips, pellets, wood chip & pellets, wet wood chips & pellets along with different temperatures and the color and smoke flavor was not exactly where I wanted it. That isn't to say the smoker doesn't make good food, but is the nature of that electric smoker.
The one thing I didn't try was I heard of some folks putting 1 or 2 lit briquettes somewhere around the smoke box and then placing a chunk of wood on that. But then you start getting into more of a charcoal smoker and so I just bought a WSM
With the MES if you are trying to get as much smoke, whether flavor or color that others get with charcoal or burning sticks you might be chasing something that might never come to be..........relatively speaking of course.
