How we compare

We do not buy the products, and we do not run them in a lab. Nothing on this site is written as if we had. When a page describes how a product behaves in use, that comes from a source we read and name — the manufacturer, the retail listing, or an independent reviewer who did handle it.

What we add is the comparison itself: the same attributes for three products, in the same units, next to each other, with the trade-offs stated plainly. Specifications are scattered across brand pages that each measure differently; putting them side by side is work, and it is the work this site does.

Three products that differ in a way a buyer actually decides between — usually a budget option, a mainstream one, and a premium or specialised one. Products are chosen before any commission is considered, and a higher commission never moves a product up a page.

We only compare products that are currently sold as new. A discontinued model is replaced when we recheck the page.

Each product has at least two sources: the manufacturer's specification page or the retail listing, plus one independent review or analysis. Every source is recorded with the date it was read. Numbers are converted so the three products can be compared in the same units, and a figure the brand does not publish is written as "not stated by brand" rather than guessed.

Prices are deliberately absent. They change daily, and a page that quotes them is wrong within a week.

Product links are affiliate links, mostly to Amazon. If you buy through one, we may earn a commission at no extra cost to you. As an Amazon Associate we earn from qualifying purchases. Links are marked as sponsored, and the disclosure appears on every article before the first link.

Commission never decides the ranking, the recommendation, or which products appear. It decides only that we can keep the site running.

Every product link is machine-checked: the link has to resolve to a live product page with our tracking tag, and the identifier has to match the exact product the article names. Once a month, every identifier on the site is re-verified against its listing, and a page linking the wrong model or a discontinued one is queued for a rewrite.

Pages are rewritten, not date-stamped. A refresh re-verifies every product, rebuilds the facts from sources read that day, and replaces anything no longer sold. The date shown on an article is the date of that work.

We do. A specification changes, a model is replaced quietly, a link points at the wrong variant. When we find one, we fix the page rather than hide the change. If you spot something, tell us and it gets fixed in the next cycle.
