Great little smoker for the price.  Reading other reviews, I did use threadlocker on the base when putting it together.  I used a high heat liquid gasket sealer around the welds on the inside, when attaching the firebox to the side of the smoker barrel and around the chimney.  Temperature is holding well on my little test run(see photos).  Added a grey felt gasket tape to help seal off around the lid of the barrel.  Slittle smoke does sneak out the back, but nothing to be overly concerned about.  
Took about 90 mins to assemble by myself. 

Been a long, cold winter in Atlantic Canada and looking forward to using this.  Can already taste the Ribs and pulled pork
