This is my second smoker from the same company. Assembly very easy if you follow an instructions. The only negative feedback is for bluetooth. Not sure if problem in the bluetooth byself or the apps. Was able to connected ones, then is no longer connected. Tried to  uninstall and reinstall the apps, not connected, asking to stay close to smoker, I'm literary put my phone next to bluetooth and make no different. Otherwise the quality of smoker by self, the heat adjustment options, the timer - all working great! Hope it will serve me for at least few years.
