After assembling my smoker had a slight problem with top aligning correctly with the bottom.  After adjusting hing screws problem was solved.  I use the smoker for pizza, brisket, pulled pork and barbequing hamburger and steaks.  I like being able to control internal temperature that ability is the big advantage of the smoker. To get the pulled pork to cook perfectly, cooked it about 10 hours at 225 degrees without adding charcoal.   Can't do that with a conventional charcoal cooker.
