Product review (5 stars): Best. Water. Ever.
Im always leery of using 3rd party products in instances like this. But I had to look at other option because holy cow are these expensive! But I just couldn't bring myself to buying the much, much cheaper 3rd party options. It worried me that they were cheaper because they don't use the same quality filtration stuff...but Im happy to be wrong.

I may have paid more for peace of mind...but I can at least say the water that comes out of my fridge is DELICIOUS. And flavorless. Which is how water should be.
