Product review (5 stars): Great Deal
I was able to buy 3 for the price of one. The manufacturer wanted more money for just one filter and they admitted that this company makes their filters and puts Samsung on the label! So far the filter is working great. From order to delivery it took 5 days to arrive, if you order as soon as the change filter light is indicating 1 month left you'll have plenty of time.
The biggest problem I had was figuring out the actual after market replacement filter for my fridge. I called the fridge manufacturer and they were able to cross reference the part number.
