Product review (5 stars): Great product, great value
For the price of this product, I think it fairly lasts a long time.  I bought my house 2 years ago with a new Samsung refrigerator and in 2 years we have only had to replace the filter twice. And there are 3 of us drinking water and using ice cubes. Easy to install and Amazon is the easiest place to purchase this without running all over town (Best Buy is only other retailer I could find it, if you are in a pinch and need one urgently you can go to a BBY store, but I find the best price for these on Amazon)
