Product review (1 stars): Might have to buy direct only
Installed new Samsung refrigerator on September 2015.  First filter I replaced 4/16/16 worked great which I ordered on Amazon.  It was the same type filter as the one that came with refrigerator. 5 months later I ordered 2 more using bar code on box from Lowes because the sale price was unbeatable at $30 a piece.  They have not worked well at all.  The UPC, item in box looked almost the same except little differences in construction which other people complained about.  I will now have to call Samsung to see what's going on.  My guess is that Samsung makes their own knock off as most companies do forcing the consumer to buy direct.  I've had issues like this in the past with other products from other companies and one customer service rep even told me that it's true.  That if you want the real deal you have to buy direct.  It's how they make their money and why other places can sell them cheaper.
