Nice even cook surface, easy to adjust/maintain Temps (even in windy conditions).  The only thing keeping it from a 5 was the lid.  It didn't fit or close just right, which could've been altered in the shipping process.  It was fairly easy to fix by adjusting the hinges, but it still doesn't line up just right.  We RV quite often and this will definitely replace the built-in cook top for the outdoor kitchen!
