Product review (1 stars): What a Waste
I bought 2.  I installed the first one and it started sputtering so I replaced it with the second one, which again kept sputtering.  I was skeptical that both filters would be defective, so I thought it was a problem with my refrigerator.  After wasting my time looking for a problem with my fridge that wasn't there, I simply decided to try a different brand.  That instantly fixed the problem, proving that these filters were defective.  Now, looking at many other negative reviews, I can see I wasn't the only one that had this problem.  Don't even take a chance on these, because customer service is very uncooperative in regards to offering a satisfactory resolution.  They'll just tell you that you're wasted money will help them "engineer a better product".
