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.
Good
Good is 5.5 to 6.4.
