Best of luck with the replacement unit. Hopefully someone at MB is following the various forums, especially this one and will take the necessary steps to once again produce a product without any safety or reliability issues. I did not mean to suggest that the secondary AMAZN smoke device was or is not a worthwhile investment. On the contrary, it was the MES I was referring to that based upon the many posts seems to have some rather serious problems. And the MES is not an inexpensive throwaway smoker. I meant no offense and hope my comment was not taken that way.
