Product review (4 stars): working great.
I bought these to replace the Kenmore brand. The only thing I noticed that are different is you need to run a little more h2o out to clear loose charcoal and they are half price of Kenmore's. I have had it in service a little over a month and water still taste great. Will follow up when I change filter. The other brand wasn't lasting a month due to hard h2o.
