Assembly took about 1.5 hours. Directions were easy to follow, clear, and concise. Was missing the bottom magnet that holds the doors closed. No big deal. Notified customer service, they replied the same day and shipped out the part the next day. Having the wireless thermometer is a MUST. It keeps you from having to constantly open the grill. Highly recommend following the various recipes on the Z Grills site. Lemon Salmon and the smoked, reverse-seared rib eyes came out perfect. Temperatures were as stated on the thermometer. I used oak pellets and the flavor was great. Looking forward to trying more recepies. Great grill and well performing.
