I put a Kenmore in my old house 27 years ago. Zero issues with it in the time I owned the house after 25 yrs. of usage, I was a softener tech with them also. Regen on it was timed via water usage.
If on well water put a sediment filter in ahead of it to stop valve wear in the unit. I used iron fighter salt in it and every couple years I ran resin bed cleaner through it. I've forgotten who made it for them. I never had to replace a part in it in that time.
