Is it true your water softener is going to break in 4-5 years here?

I have been told by Reliance(tm) people that this is the case and AI chatbots suggest it's true for the basic Whirlpool WHES and Rheem units. But if I get a premium unit from a local water place like SmartWater, it will last me 15 years.

So I want to know from those of you with Whirlpool, Rheem, Kenmore units, how long do they last before you need to get a new one? And if you have a Smartwater or other professional unit, how long do they last before you need an service call to fix something or before the beads run out and you need to buy a new bead tank?
