No store we check sells it online; the maker lists where to buy or who installs it.

Pros
  • Shows the salt level and shuts itself down in cold or very hot water, protecting the cell
  • Runs a Hayward variable-speed pump and a heater on its own, without separate automation
  • Accepts wide salt swings (1,200 to 8,000 ppm) before it stops making chlorine
Cons
  • Sold through pool pros; online prices are scarce and warranty is best with a Hayward partner install
  • App control needs the extra Omni upgrade kit
  • Low output (0.53 lb/day) for its 15,000-gallon rating
