Product review (5 stars): Easy to install
Came quickly.  Easy to install. Great price.  Water tastes much better.  Most of us don't live in a third-world country (or Flint, MI) so we're not going to be harmed by drinking water straight out of the faucet.  I buy water filters basically because my fridge water dispenser comes with a water filter feature (mindless consumer) and because it makes the water taste better.
