I bought this refrigerator in 2018.  It had all the bells and whistles I needed.  I was very happy with the product until it required periodic maintenance.  You must change the air and water filter every six months.  To my suprise, I discovered that the water filters that are recommended in my owner's manual do not fit the refrigerator.  I found this distressing because they're very expensive and I don't like wasting my hard earned money.     Fortunately, there are several vendors who sell replacement water filters that actually fit this model and work.
