I was really hoping this would be my new permanent fixture. Spent a lot of time on careful installation. The water tasted the same, but I believed it worked. But after a week of use, I didn't feel very well and could hardly digest the disgusting water, so I took out a water purity tester and did some trial tests. And I was so disappointed. The levels of contamination between the faucet and the filter are ABSOLUTELY the same. I have performed controlled tests using bottled water and other sources to ensure the test device is working properly. Yes. Bottled water showed almost 0 ppm in the TDS test, while tap/filtered water showed almost 450 (!) ppm. And you guessed it. This is very very bad. It's almost off the charts. Just below the legal limit. Reference measurement see photos. And yes, I "let it run for five minutes" when I first installed it before using it. I even reinstalled it. No difference. Very disappointing. If it's broken, I'd like to try again. I really wanted it to work. I have no idea where all these five stars are coming from. People don't test it or even assume it works and give a five star review because they want the free filter they offer in exchange for a good review. SMX
