How we score products
Every score on undig.me is a weighted average from multiple independent review sources. No single source controls the ranking.
We collect scores from 10+ review sites
For every product, we gather scores, ratings and editorial verdicts from the most respected review publications. Each source is assigned a credibility tier that determines how much weight it carries.
RTINGS, Wirecutter (NYT), Tom's Guide, Good Housekeeping
Dedicated testing labs, repeatable methodology, large editorial teams.
T3, CNN Underscored, Pack Hacker, Notebookcheck
Hands-on reviews with clear criteria, but smaller testing infrastructure.
Reddit, Amazon user reviews
Real-world ownership experience. Useful for durability and edge cases, but subjective and uncontrolled.
We normalise every score to 0-100
Review sites use different scales. Some give a number out of 10, others use stars, and some only give an editorial verdict like "Top Pick." We convert everything to a consistent 0-100 scale.
| Source format | Converted to 0-100 |
|---|---|
| RTINGS (0-10 scale) | score x 10 |
| Stars (1-5 scale) | score x 20 |
| Percentage (0-100%) | Used directly |
| Wirecutter — Top Pick | 95 |
| Wirecutter — Runner-Up | 85 |
| Wirecutter — Also Great | 78 |
| Wirecutter — Budget Pick | 72 |
| Reddit community sentiment | Manual 0-100 estimate based on upvoted threads |
We calculate the weighted average
The final score is a weighted average. Sources without a usable numeric score are shown for reference but excluded from the calculation.
Final score = sum(score x tier_weight) / sum(tier_weights)
Example: if RTINGS (Tier A, 3x) gives 85 and T3 (Tier B, 2x) gives 80, the score is (85x3 + 80x2) / (3+2) = 83.
When we update scores
- When a major new product launches in a category
- When a top-tier source publishes a new or updated review
- When a firmware update significantly changes a product's performance
- Every product page shows the date it was last updated
Editorial independence
We earn a small commission when you buy through our links. This keeps the site free and independent.
Affiliate revenue never influences scores or rankings. Products are ranked solely by their aggregated score. We do not accept paid placements, sponsored reviews, or "featured" listings.
If a product we link to has a known issue, we note it. If a cheaper product genuinely outperforms an expensive one, we say so. The data leads — we follow.
