Product review (1 stars): Worthless purchase. Doesn't fit my Samsung French Door model RF323TEDBSR, though the filter is listed as fitting this model.
I bought this water filter in March, 2014 to use when I replaced the filter in September. Every time I replace the filter, I order another one to have on the shelf ready for replacement. Yesterday however (time to change the filter), I found that the replacement I had on the shelf would not twist in far enough to lineup and seat. I even pulled the fridge forward, turned off the water and tried again to no avail. And of course my 30 day window to return this item has long since expired. I thought I was getting a good buy on this filter when compared to the price at the local appliance store, but it's worthless if I can't use it. Don't make the same mistake of buying ahead of the time you plan on using it.
