This is my very first smoker and I am very pleased.  The box came with pretty good instructions, it took me about one hour to put it together.  Initially when I purchased I thought I could connect to my gas at my home but it is not recommended because gas burns at a different temperature than gas.  I got the perfect propane tank and cooked a pork roast on y first try, it came out juicy and delicious.  I live the two doors so heat is not released when adding wood chips.  The materials used are nice and the quality and workmanship is good.  Very pleased!
