Huh...that's probably longer than most MESs' before they crap out.Mine is powered by dryer elements. Has a fan blowing across the element the whole time it's powered on. My setup is the same thing sausagemaker uses on their cookers. I don't have a ton of hours on it yet but the last 5 weekends I've done over 100lbs of hams and bacons per run. The way I'm doing hams they take about 24hrs. So between the hams, bacon, jerky and pork butts I've done it's run over 200 hours so far with no issues
