The WBA Score
How the WBA Score works
We test each bottle on what matters in everyday use, then turn the results into a WBA Score out of 100.
One score, different standards
One scale. Three scoring models.
Every bottle ends at the same 0-100 score, but the criteria adapt to the product category. This keeps the system fair: a non-insulated plastic bottle is judged on what it is designed to do, rather than being penalized for lacking insulation or other features found on stainless-steel bottles.
PERSONAL VERDICT
Why 10 points stay human
Every WBA Score reserves 10 points out of 100 for our Personal Verdict. Testing data tells us how a bottle performs, but it does not capture the entire ownership experience.
Two bottles can look equally good on paper while one is simply more enjoyable, practical, or satisfying to use day to day. Personal Verdict gives us room to reflect that real-world experience without overpowering the measurable results.

FAQ
Questions about the score
What makes a WBA Score official?
We only publish an Official WBA Score after personally testing the bottle and completing the information needed to calculate the score.
Is every bottle scored using the same criteria?
No. Every product uses the same 0-100 scale, but each bottle type has its own scoring model.
Why can two versions of the same bottle have different scores?
Size and lid configuration can change weight, handling, cleaning, leakproofness and other measured results.
Does missing data count as zero points?
Not always. Important missing results can hold back a final score instead of being treated as a failure.
Can a WBA Score change over time?
Yes. Scores can change when new test results are added or the scoring methodology is improved.
Does price affect the WBA Score?
No. Price can matter in value recommendations, but it does not add or subtract WBA Score points.
