Product review (1 stars): Knockoff or down-level design
First time posting a review, but I felt this deserved one.

I have a Samsung RF4287HARS french door fridge, for which this filter is supposed to be a suitable replacement.  Upon receiving the filter, I installed it per the instructions, and my fridge made a loud groaning noise.  This noise eventually stopped, but clearly was not normal. When trying to dispense water, I would get a little water at first, but it very quickly slowed to a trickle and then stopped.  The dreaded groaning noise would also come back on occasion while trying to dispense water.  Normal flow (with no filter) is 6 ounces in 10 seconds.  With this filter, I was lucky to get 2 ounces in the 30ish seconds it takes before the automatic kill switch kicks in.

I've purchased this "Samsung" filter, as well as several generic brands, and all of them have acted in a similar fashion.  I finally broke down and spent the $50+ for a Samsung filter from a big box store.  In visually comparing the big box filter to the one purchased from Amazon, the differences are subtle, but numerous.
- label on big box filter package says "mineral water"...label on Amazon filter package says "fresh water".
- center hole in tip of Amazon filter is tiny compared to the hole in tip of big box filter.
- structural design of filter between the two o-rings in completely different between the two.

I'm an engineer that has worked in product development for 15+ years, and in my opinion the "genuine Samsung" filter I purchased from Amazon is either a knockoff, or an older Samsung design that they have since revised/eliminated.  Keep in mind that neither the Amazon filter nor the new filter from the big box store look like my previous filter (which still works just fine), so clearly Samsung is doing design updates to these filters for some reason or another (my guess is cost reduction).

Bottom line, buy this filter at your own risk.  It was completely useless in my fridge and it's being returned to Amazon for a refund.

Update: After carefully inspecting the packaging for both filters, there are several differences.
Amazon filter - Manufactured for Samsung Electronics by 3M Purification (Mexico), graphic on left side panel is misplaced and overruns text on the package, capacity listed as 1136L/300G
Big box filter - Manufactured for Samsung Electronics by Microfilter Co., LTD (Korea), graphic appears properly centered, capacity listed as 1150L/300G.

Both filters have the exact same EAN number and UPC code.
