Review: Super easy to install with added minerals - After looking at many clips and reviews decided to go with the x12 ro filter system. Was using a previous waterdrop single filter under the sink system. After sorting out my issues re the connectors to my existing system under the sink it was very easy and straightforward to install. Even oneself as plumbers charge too much for such a simple install. Once i had the parts it took no kore than 20 minutes to install.
Review: Compact, fast flow, high filtration power! - I am very happy with the Waterdrop X8 RO System. It is compact, efficient, and fast flow with high filtration power. If it can also output different temperature hot water, then that will be perfect. I have seen some system have intelligent faucet and can produce hot water. I wonder why Waterdrop X series cannot.
