Product review (1 stars): The filter stopped working after two months, no warranty support from the manufacturer
The light on my refrigerator turned yellow so I placed an order with Amazon for these filters on January 30, 2017. The light stays yellow for a month and I replace it when it turns red. I believe I replaced this around the beginning of March 2017. A couple of weeks ago, I noticed a substantial reduction in water flow. It was taking a very long time just to fill a coffee pot. Last weekend, at the end of April, I replaced the filter with the second one. The first one barely lasted two months, and that includes a week or two of poor water flow.

I contacted the manufacturer today and explained the situation to them. They told me to contact the vendor for a refund. I told them I purchased it from Amazon and I am beyond the return period. I asked them if they guarantee these filters and they said they do when purchased directly from them. I explained how ludicrous that is. I compared it to purchasing a brand name television from a big box store that breaks six months later. The television manufacturer will still repair or replace it. This manufacturer told me they could not verify that I purchased an authentic filter. I told them I did purchase an authentic filter directly from Amazon and I offered to ship it back to them at my expense. They told me they are not setup for that and the best they could offer is a discount on a replacement filter. The discount was less than 20 percent off the full retail price so I told them no thank you.

Follow up: May 30, 2017

The second filter has failed with a substantial reduction in  water flow. It only lasted one month.
