I bought my new 4000-series washer and dryer to replace a ten-year-old LG set I had (that are still working fine, by the way). But I sold that home and left the old set there and bought new ones for my new house. They're so fancy! I didn't think I'd use the ThinQ app but with the laundry upstairs, I can be anyplace and get a notification to my phone that the clothes are done. I haven't used the steam feature yet. I'm still learning what all the different cycles do, but it's a great set and I look forward to enjoying them for many, many years.
