I've had this fridge for about 8 months. While I do love it, I have to agree with some of the other reviews...the fact that you can't stand up a large bottle of juice is absolutely ridiculous considering how much this cost. Love the freezer drawers, insta-view door and especially the auto open feature.

Good product with great features

Having Issues

I received my first Signature refrigerator at the beginning of 2019. I absolutely love the spacious room inside. It will hold a lot of product. The swipe your foot to open the door is a great feature too. The freezer doors where the doors come out when you open is awesome. My freezer started frosting up. Found out that the seal was not sealing. Product is defective. LG offered to replace. Three months later and now the replacement product is having the same issue. The ice cube maker does not produce enough ice and there could be a little more room to place gallon containers upright. If you remove a shelf then the led lights donÕt work on that shelf. I still canÕt get my WIFI to hook up with this refrigerator. With all that being said, I really like the space and the stainless interior. IÕm redoing my kitchen and LG does not make an oven/microwave combo to match the Signature series. I waited on ordering other products in hopes that this would come out. I am now waiting on another replacement fridge because it has the same defect as the original. Having issues with customer service from LG and Costco where I purchased. Still donÕt have a delivery date for the new one. On the phone going back and forth trying to straighten out for hours. LG said they gave the order to Costco to replace. Costco said that they have not received anything. You know how it goes......

We'very had the refrigerator for a few weeks now and absolutely love it starting with the ice and water. I like crushed ice and my husband likes cubes. Switching ice types doesn't put any of the prior selection into your glass. The filtered water tastes like the spring water I used to buy.The bins are great for organizing in both the cold and freeze sections and I like the way they lift out for cleaning. The freezer bins are large enough to hold a large turkey and, because they pull out, nothing is getting lost in the back. There is no wasted space.The quick through the door access section works great for grabbing items we use daily.My only complaints are the deli drawer at the bottom of the refrigerator section. You need to open both doors to access it. That should be 2 separate drawers like the rest of the refrigerator; and, the manual should have a larger font.Bottom line, every day, I say 'I love that refrigerator '.
