Methodology
How we research
We don't run a lab. Instead, we read what people who already own a product say about it, plus what independent testers found, and we summarize it with the downsides first. Every statement on a product card links to where it came from.
Where the information comes from
- Owner discussions in community forums, where we can access them.
- Retailer reviews on Amazon and other large stores, including the star-rating breakdown.
- Independent expert tests from publications that test products hands-on. We summarize their verdicts and especially their "cons".
- Maker specifications for facts such as capacity and power.
Top complaints
For each model we list the complaints that come up repeatedly (usually three, sometimes four). "Very common" means we saw it raised across several independent sources; "Mentioned often" means several mentions; "Occasional" means fewer, but notable. We don't invent percentages for these.
Amazon 1–2 star share
This is the share of 1 and 2 star ratings shown on the product's Amazon.com page on the date listed. It is a rough "regret signal", not a measure of quality on its own: ratings can include shipping problems and unit defects. If we couldn't see it, we say so instead of guessing.
Scores and ranking
Each score (1–5) is based on test results and owner reports, and you can tap it to see the reason and the source. If we don't have evidence for an aspect, we leave it unscored. The ranking uses the average score, then subtracts a little for common complaints and a high 1–2 star share.
Prices
We don't list prices because they change daily. Price tiers ($, $$, $$$) are based on typical list prices. Always check the retailer for the current price.
Money
We may earn a commission when you buy through our links. Brands can't pay to be included or to change what we report. Affiliate disclosure
Corrections
Products change, and we sometimes get things wrong. Each category page shows when it was last updated.
