It was very easy to put together. It comes with instructions but it's straightforward, just make sure you shake the dust out of the rocks before putting them in the pit.
It has a 6 feet long hose for the propane tank and it comes with a base for the tank.
It also comes with additional touch up paint, a battery for the igniter and a cover for the pit.
Build quality is very good. It's not that heavy and it feels like cement, rough and heavy duty.
