First one was a Wolverine, purchased in 1966, and moved 4 times. It gave up in 2014. 48 years!! I replaced with a Kenmore and so far it does what it needs to do and seems to use less salt. My skin can't handle the chlorine in city water so softening is a must. City?? Two blocks from the Manistee Nat'l forest with bears and coyotes occasionally visiting, but we are on the city system. Culligan is in the area, but for me, price was a factor.
