Methodology
How we choose
The ranking sites in this space lead with test labs and "10,000 research hours." We can't match that honestly, so we don't try. We compete on something a paywalled lab can't easily copy: a transparent, reproducible, spec-based method you can check yourself.
The honest starting point
We do not run a testing lab. We do not own most of the products we write about. Saying that out loud is the point — the number of products we claim to have hands-on tested is one we keep at zero unless it's genuinely true, and where a device is labeled "Researched, not hands-on tested," that is exactly what happened.
What we do instead — the four inputs
- Published-spec compilation.We read each product's live retailer listing and manufacturer spec sheet and quote the specs that decide the purchase — resolution, storage type, power, dimensions, radios — faithfully and dated.
- Manufacturer-documented compatibility.Every ecosystem claim (HomeKit, Alexa, Google, Matter, Thread, Apple Home Key) comes from the manufacturer's own documentation, not an assumption. If the maker doesn't document it, we mark it "not listed" rather than guess.
- 3-year cost of ownership. Hardware plus any monthly cloud or monitoring fee times thirty-six months. The arithmetic is shown on the page so you can check it.
- Aggregated buyer sentiment. We read the weight of verified-buyer reviews for recurring, real-world problems — clearly labeled as aggregated sentiment, never presented as our own testing.
How a pick gets ranked
We deliberately don't publish a single made-up score, because a score is a measurement and we measure nothing. Instead each pick gets a plain-language verdict, a "best for" that has to be distinct from every other pick on the page, and a mandatory "skip it if" — because a roundup where everything is great is an advertisement, and you can tell.
Prices and freshness
Prices are pulled live from Amazon's API and stamped with the date we checked them. If our data is more than 48 hours old, the number vanishes and the button falls back to "Check price on Amazon." We would rather show you nothing than a figure that has rotted. We re-verify money pages roughly monthly, and only bump the "last updated" date when we've actually re-checked.
Corrections
We get things wrong sometimes; hardware changes and firmware updates move the goalposts. When we find or are told about an error, we fix it and note it — see the editorial policy. If you spot one, tell us.
