I would have liked a better temperature control, and better production of smoke. 

The temperature settings are preset 180, 225, 250, 275, 325, 350, 375 and max. Not sure if this will really hit 500 as advertised. Also, it does not produce a constant supply of smoke. Use of a smoker tube is necessary to get a constant flow of smoke. 

It was easy to assemble. It works as advertised. It is a relatively inexpensive.
