this unit is well made and folds up so its portable.  Buy the bag for the griddle top.  Makes it so much easier to carry.  the top is very heavy.  if you season the top properly nothing sticks on it.  I've read some reviews that say the burners don't light properly or the griddle doesn't get very hot.  The regulator has as safety feature so if you do not follow the burner lighting instructions the regulator could reduce the gas flow.
