I have 2 bradley smokers and I love them.Theres no need to open the smoker once you start smoking something so your not constantly losing heat, everythings automatically fed into it from the outside.
Theres no wild temperature variations while cooking.No flame or hot coals means if Im smoking in the winter I can bring it right into the porch and use it without constantly watching it.Handy when Im doing pulled pork or something that needs to cook overnight.Also handy for items that need to cook at very low temps as you dont have temperature spikes.Can also be set up for cold smoking (havent done this yet}.
Downside is the bisquettes are spendy, and at times it would be nice to have more room in it.Ive screwed around with other charcoal, electric, and gas smokers in the past and this is by far my favorite.I will admitt though in the last few years theres been some other models that have come out I would love to play with.
