Purchased as an upgrade from an old American style which served us well. This LG fridge freezer is amazing, honestly keeps food fresher for longer. The ‘knock door twice’ is more of a novelty in my opinion probably because I know what’s in the fridge! Saying that my children use it to have a nosey before deciding what they want from it, instead of having the door open for ages previously. The non plumbed water dispenser and ice maker are brilliant too. The actual water container inside the fridge may be a bit heavy for some if filling to the max, and expect a few splashes when putting it back in, but in all it’s simple to use. The ice machine makes 2 varieties of ice at a touch of a button, really simple to use. The freezer is a good size and can store a lot of food. We as a family are really happy with the purchase and would definitely recommend to others.
