I purchased a 40-inch masterbuilt electric smoker from Academy Outdoor Sports. I used it approximately 6 to 8 times then it started tripping the GFCI. I have to reset it like 10 times then it may or may not work. Finally it just trips every time it starts to head. I paid over 300 dollars for this thing and it has not lasted at all. Very disappointed. As I read all the reviews it seems I am not alone. This thing is really a piece of junk. Was cool while it lasted but it didn't last. Damn!
