We’ve been using this for over a year now. Last March, I accidentally left the freezer door open for 12hrs. I panicked after noticing it then I saw all food was in good shape. All meat were still frozen at the back side of the freezer, wraps and other frozen vegetables still in good condition in front shelf, ice did melt. You know you have a reliable refrigerator if something like this happens. We love LG appliances. We have washing machine and television at well! LG is a very dependable brand.
