Product review (2 stars): Expensive filter, bad installation instructions
The Good News:
It seems to work. Water tastes fresh until the filter warning comes on.

The Bad News:
1. It's very expensive and lasts only 6 months. Between this and the air filter, I'm spending $100/ year on filters. Time for a cheaper brand.
2. Installation instructions on the box are wrong in 2 regards.
  - They say to push the old filter up for removal, whereas it must come down.
  - They don't tell how far to angle the old filter before pulling it out. I nearly broke the mechanism trying to remove the old one, but then found a YouTube video which explained what the instructions did not. Turns out I had to remove the top shelf to get enough room to operate.
