Product review (2 stars): Water was soooo slooooow coming out
Possible fake.  I had bought a 2 pack, the water was not coming out as fast as usual, eventually came to a trickle.  Became annoying just to fill my coffee pot in the morning.  I took it out and put the other one.  Same thing.  Eventually bought directly from manufacturer and presto, water now comes out like it should.  I'm glad I paid the few extra dollars as I had done an internet search and after confirming the water supply hose the fridge was working, the next step was to have a new pump installed in the fridge.  Turns out that it had nothing to do with the fridge, but likely the filter itself.  I think it all depends on the vendor, as I had purchased one earlier without any problems, so roll the dice with your money, if you want.
