Product review (3 stars): Low flow rate
I am disappointed with these filters.  The flow of water through the filter is very slow.  I ended up changing the first one way early because it took forever to fill a glass of water.  I made sure all the air was out before inserting the second one into my refrigerator, the flow was better but still way slower than my previous filters.  I have even had to recalibrate my auto fill feature.  Before I changed the settings, set at one cup only gave me 1/4 cup.  I will not reorder this brand again.  On the positive side they do seem to filter well.
