Product review (5 stars): Works Fine
I was concerned about how this might work since I had a problem once with a filter and had water running all over the place.  But this was a snap.  Take the old one out.  Put the new one in.  Someone said that it doesn't filter everything and that may be true but I am not concerned about that.  Just want the water to taste good and this does the trick.  I will definitely buy the Water Sentinel filter in 6 months.
