Product review (5 stars): Works just perfect!!
I was going to buy some of the cheaper off brand filters offered on this site, but decided to stick with the Samsung ones instead.  I looked at the 3 pack, but the singles are cheaper (or were at the time) when you divided out the cost.  It works great, just like it's supposed to.  I drink a lot of water, and more so when my water has NO taste like it's supposed to be.  :)
