Product review (5 stars): pricey, but worth it
$50 seems like a lot to spend on a filter that you rarely think about, but I can taste the difference in my water. It is also nice because it fits my fridge and I don't have some weird bulky pitcher or gadget to put on my faucet. It fits up in a corner inside the fridge and stays tucked away neatly while it spews out clean, cool water.
