Product review (5 stars): WARNING: Mfg Changed Threads, Won't fit Anymore.
I have a Samsung Refrigerator and I have been ordering these for years, since 2011. I find my last order, then "click" to reorder as needed. No problem  These filters claim to be a replacement part for the filter. Well now they don't fit at all. Comparing the old filter to the new filter they have changed the locking pattern in the plastic stem. I didn't even notice until I was attempting to shove it into the holder and wandered what gives? I pulled it out and looked, took photos.  I reordered thinking a fluke, no fluke, same problem What and why did the manufacturer change the pattern?  Returning the second set for a refund.  I guess I have to buy original now, which are about the price of this 3-pack for just one.  Such a major bummer.
