Waterboss Water Softeners / Model 700
If you're one of the lucky ones that get a machine that stays working then good for you. But if it fails and I'll bet it does then you're on your own.
No service. The run a round from their tech line. Grossly overpriced replacement parts.
Had several other softeners over years and all lasted 10 to 15 years. Like all appliances they do wear out. But water boss didn't make it 5 years. Resin tank failed and the 10 year warranty meant nothing.
Do yourself a favor, avoid water boss.
