Assembly: The unit went together nicely, it was apparent that it was designed with the end user in mind. Despite the large number of pieces, it went together easily, and with no curse words! 
Operation: I have only used the grill once so far to prepare some pulled pork. It worked well, but the temperature swings were larger than I expected (30 or 40 degrees from the set point). I used a separate external temperature probe in addition to the built in temperature sensor, and both read very similar. Other users report the temperature being right on, so my issue may have been weather or user related. I will continue to monitor the temperature swings. Otherwise, it worked great. Easy to use, the amount of smoke was fine for my tastes, and the end result was delicious. The only thing preventing me from giving the 5th star is the small concern over the temperature swings.
