Product review (1 stars): You get what you pay for.  Substandard product.  Not worth it.
I am going to buy a new one at Lowes this weekend.  The one I got is the pitts.  I ha done last year, I forgot to change it, 8 months, it started to like vibrate when we tried to get water, I think it was getting clogged up.  I put a new one in and it worked perfect.  It was time for a new one so I ordered this one, it works for about one or two glasses of water then starts to vibrate the lines and in the fridge, like it is clogged up.  This started on day two, just got it last week.  I have to take it out and put back in every morning so it flows smooth and with no noise or vibration on the lines.  I threw all packaging away, my problem, so that is ok.  I learned my lesson.  Saturday morning we will go and purchase a Samsung filter.
