I have two smokers, the older 4 rack model, and the new digital 6 rack model.
I am very disappointed with the 6 rack model. All the electronics are great and a big improvement, but they have the same heating element as the smaller one, and it is just not adequate to hold temperature. I have never been able to get it up to even 200 degrees, even with very little venting.
I am in Hawaii and it is out of the wind so that is not the issue.
I basically have abandon using the 6 rack model and just use my older 4 rack model.
Bad design I guess.
