We had integrated f & f, but had issues with the cabinets so elected to change to a stand alone. We thought that the knock-knock and door in door features might be gimmicky but decided to go with it. We actually liked both features from the get go. The quality of the product is extremely good and we got an extended warranty from LG into the bargain. We preferred the option of none plumbed and don’t loose too much fridge space for the 4.5L tank. The fridge capacity is still way more than a ‘normal’ fridge. We would prefer it if the freezer had all draws rather than mostly shelves but no issues with it, just what you get used to. Connected it to WiFi and have the app but not sure how much use that we actually be. Overall we are really pleased with it.
