I think they give off enough smoke to provide great smoked meat. My buddy has a Traeger and I feel the Smokin-it gives a better end product. The only true difference that would be noticed from a pellet cooker and a true stick burner would be the pink smoke ring you get.
Now, if you came from a stick burner and started using the Smokin-it, you may say it’s a lighter smoke. But, from reading about the various smokers, especially pellet cookers, I think this Smokin-it is a better buy and much easier to use, which, around we here we call it Lazy-q style smoking.
I am very happy with my 3D unit. It fits the bill for what I want and need. Would I like a big ol stick burner, yes. Do I need it for my style of smoking, no. I have my Weber kettle for that if I want. So, the smokin-it cookers should do you well.
Let me know if you have any other questions. Happy to help, as is everyone else around here!
