This fire pit was great... at first.  Unfortunately, the actual parts are incredibly cheap.  In less than a year, the knob began to stick and eventually just snapped off.  When trying to fix the knob and obtain replacement part, we discovered the screws were also cheap and couldn't remove them (no matter how we tried to loosen the screws, they just stripped).  I'm now looking to switch out all of the actual parts for the fire and try to keep the housing.  Given the price point, this is unacceptable.
