How We Rate

Every product we cover is scored on five weighted criteria. The result is the NMW Score, a single number from 0–100.

The five criteria

1. Value (30%)

Does the price match the quality, feature set, and expected lifespan? A $30 product that lasts five years can outscore a $200 product that lasts one.

2. Build quality (25%)

Materials, construction, certifications (e.g., CertiPUR-US, OEKO-TEX), and reported defect rates from verified buyer reviews.

3. Reliability signals (20%)

Volume and consistency of long-term reviews, breakdown rates over time, return rates where disclosed, and trends in recent reviews vs. older ones.

4. Suitability for the use case (15%)

Specific to each guide — e.g., for a side-sleeper pillow, this means appropriate loft and firmness; for an air fryer for large families, this means capacity and even cooking at full load.

5. Warranty & support (10%)

Length of warranty, length of return window, ease of contacting the manufacturer, and reported customer-service responsiveness.

The math

Each criterion is scored 1–10 based on public research. The weighted sum is multiplied by 10 to produce a score out of 100. We don't round selectively or adjust scores after the fact.

What this score is not

It is not a hands-on test result. We do not physically test products. Anyone claiming to physically test hundreds of products across dozens of categories is either lying or running a team you'd see credited on the page. We aren't that, and we say so plainly.

How we choose what to cover

We pick categories where (a) a clear "best for this specific need" answer exists, (b) the products are widely available on Amazon, and (c) verified-buyer review volume is high enough to draw reliable signal.
