| Chlorine output | 2.0 lb/day |

Pros
- The cell economics that win the calculator: a $699 cell rated 15,000 hr (CircuPool calls it ~50% longer-lasting than other brands) works out to ~$100/yr — a fraction of Pentair's ~$300 or Hayward's ~$220
- No DIY-install penalty: buy it online and install it yourself without voiding the 7-year warranty — unlike Pentair and Hayward, which limit or void warranty on online/self-installed units
- The most-reviewed system here at 4.5★ across 341 Amazon ratings — proven, and well clear of Pentair's early-batch 3.7
- Highest output (2.0 lb/day) and biggest capacity (45,000 gal), so it's already oversized for a typical pool — exactly the headroom the 'oversize the cell' rule calls for
Cons
- Direct-to-consumer brand with a smaller local dealer/installer footprint than Pentair or Hayward — more of the install and troubleshooting falls on you
- Local pool techs reach for Hayward parts by reflex, so it has less name recognition on the service side
- Pricier system (~$1,695) than CircuPool's smaller EDGE line — for a typical or smaller pool the EDGE-25 is the cheaper, right-sized buy
