Low range. User interface lacking ### 5/5 — Helps *2026-06-27, version 6.18.2* Works will to remove water impurities ### 3/5 — Functional but… *2026-06-26, version 6.18.2* Really needs a UI/UX update. ### 1/5 — About a year plus in and problems *2026-06-16, version 6.18.2* We will see how support goes ### 5/5 — Best thing ever *2026-06-11, version 6.18.2* I was able to install the system myself. The company helped me with the settings and my water feels is so soft. It feels like taking a shower with lotion. ### 3/5 — Good *2026-05-25, version 6.18.2* Good app. Wish it would notify me when salt level drops too low. ### 1/5 — False reporting *2026-05-06, version 6.18.2* My unit shows water use while we’re away and the water main is off.
