Just got this a few days ago. I like the size, stability and features of this smoker. I opted for propan because I don't trust the wiring in my house to handle the draw from an electric and didn't want to constantly reload charcoal.
The day I tried this it was about 45 degrees and very windy. I used a thermos thermometer for monitoring the temp. As it turned out the temp gauge that comes with the unit is totally unreliable. 
Taking into account the won't conditions, I still found that I could maintain my desired temperature range (220-230) with some minor adjustments. At the lowest valve adjustment with the gusty conditions I did have to relight it 3 times. I would suggest if possible to shield this unit from the wind if possible. With the exception of the temp gauge and possibly shielding the burner from the wind better I had great first time results with this smoker. I did 2 small pork loin and a Chuck roast at the same time.
