1) Box arrived well packaged (professionally) & quickly.
2) All fittings required were included. No leaks with hand tightening!
3) Install was simple (clear instructions with visuals).
4) Water flow is highest (UC Ultra) I've seen for 3 stage systems.
5) Manager is eager to help you with any questions you may have.
1 point for constructive criticism is faucett packaging is such that the blue hose coming out of faucett was kinked, box is a tiny bit too small.
