Review methodology

This page explains how products are assessed in our reviews and comparisons, and how that differs from the Comparezi Score.

What a review is based on

• Recorded specifications. Each claim traces back to a stored value and its source, shown on the product page.
• Context within the category. A product is judged against others in the same category and price range, using the same specifications for all of them.
• Price history. "Good time to buy" style advice uses recorded prices only. We say "lowest recorded" only after at least 30 days of history.
• Who it suits. "Best for" and "Not ideal for" come from the same rules as the Find my product questionnaire, so they can be checked.

We say in the article when a reviewer has used the product themselves. When they have not, the review is an analysis of recorded data and says so.

The Comparezi Score is not a rating

The score is calculated, not awarded: specifications are placed between the lowest and highest value in the category and weighted by published, versioned weights. It never uses reviews, prices or commissions. The full method is on the score methodology page.

User reviews

Reviews from visitors are held for moderation. Only approved reviews are shown or counted, and only they can produce a star average. We do not edit what a reviewer wrote except to remove personal data or abuse.
