I was a bit disappointed when I first bought my MES 40 at Sam's only to see it replaced by a new model only a couple weeks later. Now, that I see all the problems people are having with the newest generation, I'm thrilled that I was able to get one of the last of the old generation smokers. Mine just works. Temps always very close to my readings on the Maverick 732, and now with the
AMNPS It's damn near perfect! If you can find an older model MES 40, i would go for it.
I hope
Masterbuilt can get the problems worked out so that everyone else's MES works as good as mine. Good luck fellows.
