The unit was Very easy to

The unit was Very easy to install. Instructions were clear and easy to follow. The performance of the system is adequate for our water needs. I like the TDS meter on the faucet so you can keep track of the water purity. Just installed it a few weeks ago so I have no comments on filter longevity yet.
