Product review (4 stars): it works, like others
I've been using this filter model for two years. I'm on my second unit. It works about the same as other inline filters I've used with regard to taste of the water. It seems not to last as long, but maybe my waster quality has changed, but it lasts long enough considering the price. I do like the quick connect fitting system. My filter is located in an awkward location, and not having to snug up compression fitting anymore to copper tubing is a big help.

I've read other reviews comment on black particles.  You have to flush out the filter before you hook up the outlet end to your refrigerator. Just like any other filter. Maybe a gallon at most. I just do it until I don't see black particles coming out. The instructions say to do this as well, but I think it says to use more water. That's just CYA though.
