Well, I'm glad y'all had better luck with their SUPPOSED Customer Service than I have.
Mine is 3 weeks new and it was the last one that Sam's had.
Brought it home, seasoned it per directions, smoke coming out of the top of the glass. WTF?
Next day, I went to smoke a couple pork butts. Set the temp at 275 and checked the grate temps with the ET-732 after about an hour. 230 max on the hottest shelf.
Since then, I have sent their CS 2 emails and called twice. Nothing!!! It's been 3 weeks.
Sam's has a return policy, this is going back and I will never get another MB product again.
Maybe that's the reason Sam's discontinued carrying them. Too many returns for junk equipment.
JM2C and YMMV
Oh yeah, it shocked the he!! out of me too. Don't touch anything metal unless you like getting zapped.
