This unit is truly set it and forget it. Prep/Rub your meat. Put it in the smoker with the probe in. Add chips to the hopper. Set the Temperature and Time and go watch the game. Check in every hour or two to add chips. Timer is done? So is your barbecue! Enjoy! Easy to clean as well, particularly if you line surfaces with aluminum foil. Easy and Reliable. Definitely get the cover if you keep it outside.
