Luv that you have numerous options to use to dry for certain type and size of amount of clothes. Can not provide opinion of the amount of gas used, still in the 30 month, will not know till after. Luv the style of lint tray, catches the smallest amount on each load, this will assist in keeping the dryer vent clean for a longer period of time. Only complaint is the ring at the end of each cycle we should be able to increase the sound to hear and or turn off. Not sure if the off option is available. Other than that, great appliance so far.
