Product review (5 stars): This unit ROCKS!
This was a replacement for a unit I purchased with my washer/dryer 4 years ago. Results to me are stunning. I expect to get 3+ years of service from this unit. Zero cost for soap, softeners etc. I live in SD (NOT the softest water?)
 The person I bought it from lives in Ohio and claims 5+ years of service. My wife and houseguest love it. What else can I say? This unit ROCKS!
