Product review (1 stars): Buy the real thing, I guess...
I just received my second one of these in the mail and still having the same problem with very low water pressure coming out of the fridge. Both of these filters have been plugged up or something which is not letting the water through. When I use it, there is a whining sound coming from the filter as well. It's installed correctly with no leaks.  Customer service told me to soak it in water for 10 min and then reinstall. I've done that 3 times now. Each time the water pressure is good for about a half glass of water than it goes back down again.
