This water softner was easy to install by my husband. We have only had it for a few weeks, but, I can already see a difference in hard water stains and my showers. I feel so much cleaner with the softer water. Here in AZ. our water is very hard.  We talked to a plumber friend who told us to get GE.  We had a different make and it only lasted 5 years. Our neighbors  have a G E and it is all ready 10 years old. I love that it is easy to understand and very very quiet.
