I purchased this LG dryer to match the LG washer I purchased last year due to the fact of its good reviews and my satisfaction with the washer. The unit looks & works well, quiet and from I can see efficient. About the only setting I don’t use is the “energy saving” setting, where the machine just uses air to dry the clothes at first, then heat, if you don’t mind your clothes being damp it’s fine. To my knowledge the dryer will use more electricity, which costs more than gas, to run the machine longer. I do use the WI-FI option on both, I find it very useful, PS I also have a LG refrigerator with Wi-FI also, although there are not a lot of things you can do with wi-fi the settings now being used work just great. Overall I am more than happy I have chosen LG as the manufacture of my appliances.
