Simply put... very poor quality. First one I purchased had a completely broken resin tank and housing straight out of the box...returned to store. Got a second one, nothing structurally broken this time.... but after install and multiple issues, troubleshooting found turbine not reading water flow causing no auto regeneration, brine tank has extremely high level of water, and after manual regeneration there is very high level of salt at faucets requiring water to be ran for multiple minutes to clear each time. System is no longer softing water. This after only couple of months of use. Followed all instructions and troubleshooting steps in manual.
