Product review (2 stars): Something wrong with Amazon's batch
The filter that came with my Samsung refrigerator functioned great for over 6 months, I bought a second one at Lowes for far too much and it worked great for another 6 months.  I then purchased two from Amazon for a great price, but each of them slowed to a trickle (45 seconds to fill a glass of water) within a month.  I tried going back to my local box store expensive filter and it has been going strong for 4 months now.

I'm not sure if Amazon got a bad batch or if they get an inferior quality product, but beware.
