JHautz:

Yours did the same thing my first one did. I probably had 6 or 7 hours of use on it and it just died after I stopped for a battery swap. Nada, nothing zilch.

The other just went up in smoke. Knocking on wood that the one I have in the car now continues to work until the new batch comes out. Castle also has my old MM too, so hopefully I will get that one back soon.

I am on my 3rd MMM. I can't afford to purchase a fourth, particularly if I don't even know if it will last. If this one fails, I am going to be out of service for a while.
