It all went together exactly like the installation directions, which were clear and easy to understand. My wife is a picky water drinker and her choice of water is Nestle's pure life. She dislikes some of the more expensive cliche' waters so I had some reservations about purchasing a system only to have her not like it, but for the price I could throw it away and not have it bankrupt me.
Installed it yesterday, filled and drained the tank twice, and went to bed. This morning I go to the kitchen and find a happy face note stuck to the faucet saying "I like it!". I also bought a tds meter to test my ro water, which is 25 tds, and used it to test some bottled water. Found out that some of the expensive waters that taste like dirt, register on my meter like dirt too! Nestle pure life was one of the better waters tested and it recorded a 35 tds.
We've both had 5 stage ro water in the past and found it to taste very bland so I had my doubts that the ph filter would fix the problem, but it sure did! If my wife is happy, then there's a very good chance that you will be too!
Update:. It's been a year now and I'm still using my original filters and our water still tastes great. TDS meter reads 18 filtered and 168 tap water. There's just the two of us and it's used for all drinking and ice. No leaks, no problems. We'd give six stars if we could.
