We like this fire pit, though the pit itself is rather small.  There is room for the manufacturer to make the pit diameter a bit wider.  Additionally, the instructions should state that when lighting it, the control knob needs to be depressed - not just turned to "on", Further, your customer service reps should know this as well and inform the customer when a customer calls about the unit not lighting.  It does light right up when the control knob is turned to "on" and the knob is depressed when pushing the ignitor, One other point, the instruction manual also should include that following assembly, when attempting to set the 20# propane tank into the cavity, one should lift up or remove the burner.  Otherwise, there is no way to insert the propane tank.  I know the manual states that one can remove the burner if desired, but it's actually necessary for the burner to be lifted up out of the way.
