Initially I was pretty pleased with my water softener purchase, QWT seemed to check all the boxes. Then the it stopped working 6 months later. They apparently have only one technical support person... in the Philippines with rosters crowing in the background. Honestly, I have never seen anything so unprofessional! To boot, the softener still is not working properly and no one responds to my emails and good luck getting someone on the phone, other than sales staff. Seems like I got duped and no one is accountable.
