I purchased a DigiQ DX3 for my 22” WSM. I have used 3 times and have not been pleased with the results. Does anyone actually use this product and have success? I have followed the directions to a “T.” All bottom vents closed, top vent barely cracked, vent on fan unit half and fully open, the vent hole inside unit is not blocked, let smoker come up to temp before plugging fan on, etc. I can never get the temp to stay above 200 and the fire always goes out. I have to babysit smoker all of the time, way more than I did beforehand. The only other thing I can think of is that I have too much charcoal in the unit so air doesn’t come up. Any thoughts or input? If you aren’t supposed to use a lot of charcoal, then I’m assuming you have to refill every 2 hours or so.
