I just purchased the MES 30 at Cableas a few weeks ago and I have smoked a couple things so far. I did have a problem over the weekend with my jerky. I wanted to smoke it at 140 but the way the chip holder was designed, I could not get the chips to ignite at such a low temp. I was using DRY chips. The slot where you put the chip holder into has two brackets along the slot on the sides, preventing the chip holder from touching the heating element. Does anyone else have this problem. I think I may need to remove the pieces so my holder makes contact with the element.
