Glad you joined us Tracy, welcome to the the PelletSmoking forums!
My wife and I just got one the beginning of this month so we have probably only used it a few times just short of a dozen. But from what we have found it is running very accurate; within a few degree's of we have set it at even with 15º outside temps and 15 to 20 mph winds. We do have a thermal jacket for it and park the Yoder with its back to the wind so the thermal jacket provides the most protection possible. It would have been best to move the Yoder out of the wind, but that option wasn't very easily available to us. In my opinion for my wife and I it was a solid strong choice.
