How We Research

What we are — and what we are not

We are a small editorial team curating the best tech in each category. We are not a hands-on testing lab, we do not have an anechoic chamber or a calibrated dynamometer, and we do not pretend to. Sites that do — RTINGS, Wirecutter, Notebookcheck, DXOMARK, Tom's Hardware, GSMArena — already publish excellent measured data, and our job is to read all of it, weigh it against real-world owner feedback, and tell you what to buy.

Our four-stage research process

1. Source the lab data. For every product on this site we cross-reference the published measurements from the major independent test labs in that category (see the list below). When labs disagree, we say so.
2. Read the owner reviews. We read at least 100 verified-purchase reviews on Amazon plus the relevant subreddit threads (r/headphones, r/laptops, r/iphone, r/Android, r/Roborock, etc.). We weight long-term owner reports heavily — a six-month review is worth a dozen day-one impressions.
3. Cross-check pricing and availability. Prices are pulled from public retail listings and refreshed regularly. We flag products that are routinely out of stock or that have a substantial gap between MSRP and the price most buyers actually pay.
4. Synthesize a recommendation. Each product page and comparison is written against the same scoring rubric — performance / battery / build / value / software — and the verdict reflects the consensus of the sources we cite. Where we disagree with the consensus, we say so explicitly.

Sources we rely on

Every category leans on a different mix of primary sources. Here are the ones that do the heaviest lifting on this site:

• Headphones & earbuds: RTINGS (frequency response, ANC isolation curves, microphone tests), SoundGuys, Reddit r/headphones long-term threads, Amazon verified reviews.
• Laptops: Notebookcheck (sustained CPU/GPU benchmarks, display calibration, battery life under standardized loads), The Verge, Ars Technica, MacRumors, and Reddit r/laptops / r/macbook for long-term reliability reports.
• Vacuums: Vacuum Wars and Modern Castle for standardized debris-pickup tests; Reddit r/Roomba and r/Roborock for multi-month owner reports; Consumer Reports where accessible.
• Smartphones: DXOMARK for camera scoring, GSMArena for measured battery and display specs, Notebookcheck for SoC sustained performance, Reddit r/iphone and r/Android for daily-driver reports.

When a sentence on this site refers to a specific measurement ("25–35% ahead on multi-core CPU", "80–250 Hz ANC rejection", "10,000 Pa suction"), that number traces back to one of the sources above or to the manufacturer's published spec — not to a test we ran ourselves.

What our scores mean

• 4.7+ — Class-leading. The cited sources converge on best-in-class performance with no significant weaknesses.
• 4.3 – 4.6 — Excellent. Recommended for most buyers in the category.
• 4.0 – 4.2 — Solid. Has 1–2 notable limitations but earns its price.
• Below 4.0 — We don't recommend it. We still publish the page so you can see the reasoning.

What we will not do

• We will not claim hands-on testing we did not perform.
• We will not publish manufacturer talking points as if they were independent findings.
• We will not publish reviews whose conclusions were generated by an AI without human review and approval. Software helps us aggregate prices and specs; the verdicts are written by humans.
• We will not recommend a product we would not buy ourselves for a friend or family member in the same situation.
