Product review (2 stars): Terrible filters
I wanted these to work, I really did.  They did indeed fit perfectly into my Samsung refrigerator, and I was very excited because of all the positive reviews.  Also, note that I did reset my filter by holding the button down until it beeped.  They work great for about a month.  The problem is that they are supposed to be good for 6 months or 300 gallons.  Not so much.  After about a month (and maybe 50 gallons) the flow through the filter had slowed to a trickle that would literally take several minutes to fill an 8 oz glass.  But it's a 3-pack, right?  So I replaced the first one thinking maybe I just got a bad one.  Same thing with the second one.  It's been about 3 weeks and the family is getting water out of the tap because nobody has time to stand there for 5 minutes to fill up their glass.  Going to replace it again soon, but at 3-4 weeks per filter these get really expensive, not to mention wasteful.  I guess I'll be going back to Samsung filters...
