I found this smoker had too many parts I had to assemble.  When I first opened the box, it seemed is if it was going to be an easy project; however, the contents in the box kept going.  I am very capable at mechanic thinking and putting things together; but I don't want to spend 1/2 a day putting something together.  
Also, I found some of the construction to be subpar, such as the seal on the lid.  This is my first smoker, so maybe this is not a big deal....
Overall, the smoker did a good job, and I added some hickory I purchased from the hardware store.
