Product review (4 stars): Acceptable at the Amazon price, use twice
I'm not big on replacing filters very often. Whether it is a refrigerator, vacuum, or furnace. It just feels like I'm getting ripped off for a perceived maintenance item. I bought this Samsung water filter through Amazon for about $30 instead of $50 plus. It's worked out fine. It lasts for about six months. I take it out and put it back in for another six months. I don't taste any difference and the refrigerator is tricked and shows as a new filter.

Rating: 4 out of 5 stars for not lasting very long (if you follow the instructions) and the cost.
