How to read a Showdown Score™
The only score that counts how often a product breaks, not just how owners feel about it.
- Three parts add up to the score: what owners rate it, how often it fails them, and whether a credentialed tester backed it.
- Bands: Exceptional 8.5 and up, Excellent 7.5, Very good 6.5, Good 5.5, Fair 4, Poor below 4. Every score is dated.
- Price, the warranty and what a link pays us stay out of it.
Very good
Very good is 6.5 to 7.4.

Pros
- 4.6★ across 139 owners — no free-product reviews among those we could read
- $160 under the comparable Hayward
- Price holds at $1,439 across Amazon and the dealers, so the number is real
- Four elements and a clamp ring owners consistently praise for access
Cons
- Buy the plain (non-EC) SKU online and coverage drops to 60 days — the prefix is the warranty
- Third-party seller, so authorized-reseller status still has to be confirmed
- No route to a multi-year term without registering with a qualified installer inside 60 days

Record
- — Critical pass, and the number is unusually good: four critical reviews in 139, the second-lowest rate in the roundup, on a base with no free-product (Amazon Vine) reviews. But arrival damage does not show up there. Three separate owners describe the unit arriving chipped or broken and still rate it well, so the complaint lives in the positive reviews where a critical-only read would never find it. One owner reports two hairline cracks at the base after 18 months.
