Methodology

How products are sourced

We collect listings from eBay via the official eBay API. We never scrape prices manually or duplicate listings between sources — every product on this site corresponds to a real offer that was listed when the data was collected.

Listings can end after the data was collected (sold or removed by the seller). Always check availability on the marketplace before purchasing.

How products are ranked

Our category and subcategory pages organize listings around the dimensions buyers actually search for — product types, brands, number of channels, software.

Within each category, we rank products primarily by listing quality signals (rating count, review density, listing completeness) rather than by price alone. Cross-category relationships (e.g. "related to Beginner") are mapped by topic and keyword overlap between categories, so the cross-links you see are relevant rather than random.

How reviews are written

Each product page carries an editorial review composed of an "About this product" summary, an "Our take" assessment, and a structured pros & cons list. These are compiled by our editorial team using the product's specifications, listing details, and the broader category context. They are not the result of hands-on testing.

Where a product has third-party rating data (e.g. a marketplace star rating with review count), we surface that alongside our own assessment so you have both signals in one place.

What we don't do

• We don't physically test products. We're a comparison and curation site, not a test lab. Our assessments draw from listing data and category context.
• We don't accept payment for placement. No marketplace partner can buy their way onto an editorial list or change the order in which products appear.
• We don't show sponsored results as editorial. Anything you see in our category and subcategory lists is ranked by editorial signals, not advertising.
• We don't claim live pricing. Prices are not live. The "Prices last verified" line in the footer shows when the data was collected; always confirm the price at the marketplace before purchasing.

Data freshness

Categories, product lists and prices reflect the date shown in the "Prices last verified" line in the footer. Prices and availability may have changed since then.
