This page explains exactly how we arrive at a recommendation and how the BRD Score is calculated. If you want to know why a product ranked where it did, the answer should be here. If it is not, tell us and we will make this page clearer.
Our approach, stated plainly
We do not conduct physical product testing, and we do not operate a lab. We say this up front because a great deal of the internet implies otherwise.
What we do is structured research and analysis. We define what matters in a category before we look at products, gather evidence from sources that can be checked, weigh that evidence against a fixed set of criteria, and publish the reasoning alongside the conclusion. Where a claim originates with a manufacturer rather than an independent party, we attribute it to the manufacturer.
This method has real limits. We cannot tell you how a drill feels in your hand, and we will not pretend to. What we can do is tell you which model has a documented history of bearing failures, which brand honors its warranty without a fight, and which product is quietly the same unit as one costing forty dollars less.
How we pick the products we consider
Before we open a single product page, we write the criteria for the category. That order matters. Criteria chosen after the favorites are picked exist to justify a conclusion, not to reach one.
We then build a candidate list from products that are currently available in the United States, sold through mainstream retailers, and supported by enough independent evidence to evaluate. Products that are discontinued, unavailable, or too new to have any ownership history are excluded until that changes.
From that list, we narrow to the products worth writing about. A guide with twelve entries usually means nobody made a decision. Most of our guides recommend between five and eight.
What we look at
Our evidence comes from manufacturer specifications and technical documentation, published safety and industry standards such as those from UL, ASTM and CPSC where they apply, owner reviews gathered across multiple retailers rather than one, professional and trade publications, warranty terms and documented support behavior, recall and safety notices, and price history over time.
We give more weight to reports from owners who have had a product for months than to reactions written in the first week. Anything can look good on day one.
The BRD Score
Every product we rate receives a BRD Score from 0 to 10, shown to one decimal place. It is calculated from five weighted criteria that are the same in every category, so a 8.4 in Kitchen means what a 8.4 means in Tools.
| Criterion | Weight | What it measures |
|---|---|---|
| Performance for the job | 30% | How well the product does the specific task people buy it for, including capacity, power, speed and consistency relative to its class |
| Build quality and durability | 25% | Materials, construction, documented failure patterns, and how the product holds up over months and seasons rather than days |
| Value for the price | 20% | What you get relative to what you pay, judged against the current market rather than the list price |
| Ease of use and setup | 15% | Assembly, controls, cleaning, storage, documentation, and how much friction the product adds to ordinary use |
| Support and warranty | 10% | Warranty length and terms, parts availability, and documented evidence of how the company behaves when something goes wrong |
Each criterion is scored from 0 to 10, multiplied by its weight, and summed. A product scoring 9 on performance, 8 on build, 7 on value, 8 on ease of use and 6 on support earns:
(9 × 0.30) + (8 × 0.25) + (7 × 0.20) + (8 × 0.15) + (6 × 0.10) = 8.0
The score is never generated automatically, never randomized, and never adjusted because of what a product pays us.
What the numbers mean
- 9.0 and above. Exceptional in its class. We expect most buyers to be satisfied.
- 8.0 to 8.9. Strong recommendation. Any weaknesses are minor or affect a narrow group.
- 7.0 to 7.9. Solid choice with real trade-offs that we name in the guide.
- 6.0 to 6.9. Works for specific needs and budgets, but there are better options for most people.
- Below 6.0. We do not recommend it. Products in this range appear only when there is a reason to warn readers about them.
Scores are comparable within a category and roughly comparable across categories. They are not a substitute for reading the guide. A 7.8 that fits your situation beats a 8.6 that does not.
What disqualifies a product
Some findings remove a product from consideration regardless of how it scores elsewhere. An open safety recall that has not been resolved. A documented pattern of failures that create a hazard rather than an inconvenience. Missing certification where a category requires it. Review manipulation serious enough that we cannot trust the ownership evidence.
When we exclude a product that readers would expect to see, we say why in the guide.
Who is not a good fit
Every guide names who should not buy each recommendation. A guide that only lists strengths is an advertisement wearing an editorial costume. If a product is loud, heavy, hard to clean, or overkill for the person reading, that belongs in the review as plainly as the strengths do.
How often we revisit
We review published guides on a regular cycle and whenever something changes the picture: a new model, a discontinuation, a recall, a meaningful shift in reliability reports, or a price change large enough to alter the value calculation.
Every guide shows the date it was last updated. When an update changes a recommendation, we change the guide rather than leaving an outdated pick in place with a fresh date on top.
Money, and why it does not move the score
We earn commissions through affiliate links. Commission rates differ between products and retailers, and those differences have no input into the BRD Score. The formula above contains no term for what a product pays us, because there is no honest way to include one.
When the best option in a category earns us nothing, it still ranks first, and we point out that we earn nothing from it. Details are on our Affiliate Disclosure page.
Corrections
If we have a specification wrong, a score that does not follow from our own criteria, or a recommendation that no longer holds, tell us through our contact page. We correct factual errors promptly and add a dated note when the error was significant enough to change a reader’s decision.
Our broader standards are described in our Editorial Policy.
