Actually these filters are fine - They are worth 5 stars - If they work for you. They didn't work for me even though they were a DIRECT REPLACEMENT for my existing iSpring system. This is because they changed the connector on the end of the FT15 filter from a screw-in end to a fixed locking connector. To use it with my system (which includes an alkaline filter above) I need a U-connector. I HAVE a U fitting, but it won't work with the new FT15 filter (as many reviews of this filter indicate) without a 90 degree elbow (which was NOT included with this kit). I had to order a two pack from the iSpring website for $5.50 PLUS SHIPPING. Unacceptable. But unfortunately I'm stuck and have to do what I have to do to make the system work.
