Product review (4 stars): They work if you can swallow the cost
It works good, but is ridiculously priced. I wasn't planning on spending $100 a year of stupid water filters. I had a small gap in between the old one being removed and the new one going in. The water tasted terrible in between, worse than tap water which is concerning. The fridge definitely added it's own taste that it needs to filter out with these. But I can assure you they are working.
