Product review (5 stars): So far, so good.
It was ordered as a replacement cartridge for the original filter in our Samsung 3 door fridge. The reviews and price were the main reasons we wanted to give it a try, since Samsung models are $49.99 retail price. It is working very well to filter out those "bad minerals" and contaminants. I drink a lot more water and my coffee/tea taste better. I have only had it for about a month, so I hope it keeps doing a great job.
