1Step 01
Start from the need, not the category
Start from what should change: a lower electricity bill, quieter operation, a shorter braking distance. The section filter and search narrow the catalogue to the category that answers that problem.

How to read a ranking for your own needs
The overall score is a shorthand. Below is how to read a ranking for your own situation: which number to check first, when a difference stops being meaningful, and what the terms in the tables actually mean.
Reading order
Five steps, in this order
Each step removes products that cannot answer your problem, before the score is used to separate the ones that can.
2Step 02
Check the key parameter, not only the score
Composition and specification is one of four components. A product with a high overall score but a mediocre composition score usually wins on price or on reviews — not on what is inside.
- 9.8Composition & spec
- 9.7Evidence & studies
- 9.6Owner feedback
- 9.3Cost and value
Equal weight · 25% each. The overall score hides which component carried it.
3Step 03
Look at total cost, not the shelf price
A cheaper washing machine can cost more within a few years. Where a product creates spending after purchase — energy, filters, cartridges, subscriptions — we count it alongside the price. That often reverses an order based on price alone.
- Energy
- Consumables
- Servicing
- Subscriptions
4Step 04
Do not compare across categories
A score of 8.8 for a tyre and 8.8 for a laptop describe entirely different things. Scores are comparable only within one category.
- 8.8Tyres
- 8.8Laptops
- Not comparable
5Step 05
Put two products side by side
A gap smaller than 0.3 points falls inside the significance threshold — at that point, decide on price, warranty and service availability.

Inside the ±0.15 band these two are equivalent on quality. Decide on price, warranty and service availability instead.
Glossary
The terms we use
The same five terms appear in every ranking table on the site, with the same meaning in each section.
- BPR score (0–10)
- The mean of four component scores: composition and specification, evidence and studies, owner feedback, cost and value. Calculated identically in every section.
- Key parameter
- The single measure that decides usefulness in a given category — braking distance for tyres, wash performance for washing machines, real-world speed for broadband.
- Cost and value
- Purchase price set against what the product offers, together with costs incurred after purchase: energy, consumables, servicing or subscriptions. The horizon matches the typical lifespan of a product in that category.
- Verified feedback
- A score covering verified owner reviews and fault reports collected for the model or series.
- Significance threshold
- The ±0.15 point band within which a difference in scores is not treated as meaningful. Products inside it are considered equivalent.
