Product review (1 stars): Shorter lifespan = More cost in the long run!
I purchased this as an alternative to the expensive Samsung replacement.  I was pleased with the purchase.  It did not leak, the water tasted wonderful, and all seemed well.  Five months later, the filter light is already on.  The original one lasted 19 months, just while I've owned the home (not sure when the previous owners replaced it), before the filter light came on.  So, I would need at least 4 of these generic filters to last as long as one Samsung OEM filter. This equates to doubling the cost.
