Product review (5 stars): Water tastes great again!
When the previous blue models were discontinued, I started looking for cheaper alternatives because these new models are quite expensive.  However, I found that the water from my refrigerator had a strange after taste with each "cheap" model I tried.  So much so, that I did not bother keeping them the full 6 months.  Today, I popped this one into the refrigerator, ran about 2 gallons through it and the difference was immediately noticeable.  The water tastes as it should without any after taste.  If anything should change, I will update this review accordingly.  Otherwise, this is the model I will be sticking with.
