Product review (1 stars): BEWARE - Filter can cause pricey malfunctions to fridge.
We bought these replacement water filters not knowing they were a generic or knock-off brand.  The first water filter ran very ineffectively for about a week and then stopped working.  We took the filter out and used the water in the fridge without a filter.  It was at this point that our ice machine in our fridge stopped working and hasn't worked since.  BEWARE-- This product can ruin other mechanical functions of your fridge.  We called Samsung and they walked us through a couple trouble shooting procedures with no success.  This fridge is less than 4 years old and we have NEVER had problems with the ice machine before using this water filter.  Unfortunately it seems now that we will have to pay a repair man to come out and inspect/repair the water filter for a hefty price no doubt.  Personally I feel that the company Refresh should pay for this since I am certain the malfunction is due to their faulty water filters.
