Grilling efficiency A+.  ever thing else F.  Currently had older genesis series which I rebuilt twice before it to the point I couldn't.  Bought this unit which does the basic grilling part very well BUT, you put the tank inside of the unit making it way harder to change and took away half the storage capacity.   In addition you removed the customer friendly weight sensitive  mounting that told you how much gas was left so I had to go and buy a third party gauge at an additional expense  (which you don't offer).  Furthermore you added a brace to the floor pan (not present in the older model) which effectively cuts the remaining storage space in half again.  I guess you have gone the way of every other US manufacturer that needs to cut cost without regards how it affects the consumer.  In that regard I am positive this review will not be responded to but at least I feel better getting this of my chest.
