Product review (1 stars): Waste of money
This filter was a complete waste of money.  I tried it thinking I could save from paying for the genuine Samsung filter, but it seems this is another time that you get what you pay for.  The filter worked normally for a few minutes after installing it.  After that the water flow slowed to a trickle, to the point where it took well over a minute to fill a glass of water.  The genuine Samsung filter only takes about 15 seconds to do the same.  After a few days I couldn't take it any more and ended up buying a new genuine filter.  My sanity was restored shortly thereafter.
