Have cold smoked Bacon and Salmon and what a difference it makes in regards to taste. After slow smoker is done, i make sure to clean and oil the slow smoker for next time and so far i have had no problems. I have a set of ribs in the freezer and when it get close to july 4th i will give it a try for smoking using this device and i believe i can get 3.5 hours of smoking. Make sure once the wood chips in the slow smoker get ignited, disconnect power supply since it is not needed anymore and prevent it from burning out.
