I have/had a 40 MES. Last time I used it a few weeks ago was a bad experience. I was smoking 2 Boston butts for my sons bday party. We were all under the carport and my son (age 3) leaned against my smoker and instantly fell to the ground and was screaming in pain. Now I'm a tough love kinda father so I looked at him and said don't touch it again, it's hot. Now I've never felt it get hot enough on the outside to create that much crying so I figured he was just trying to get attention. Several hrs later it was time to wrap the butts so I reached in to pull them out. My exposed skin touched the rack and I jerked my hand back, dropping the meat. It gave me a pretty good electric shock. I closed the smoker and while doing so, touched the outside of the smoker and was shocked again. I unplugged it and checked for wear on the cord and found nothing. Costumer service had me cut my cord off and mail it to them. When they receive my cord they are going to ship me a new smoker. Can't wait to get it so I can get back to smoking. Anyone else had this problem???
