Our recommendations are built from documented research, not invented product testing. The purpose of this methodology is to make our process and its limits visible.
1. Define the use case
We begin with the shopper's problem, environment, budget range and constraints. A feature matters only when it improves that use case.
2. Build a candidate set
We identify current U.S. models using manufacturer pages, manuals, support documentation, retailer listings and established category coverage. Inclusion in the candidate set is not a recommendation.
3. Compare consistent criteria
Criteria vary by category but commonly include dimensions, compatibility, setup, core capability, maintenance, consumables, warranty, support and recurring costs. Safety-related claims are checked against authoritative guidance where practical.
4. Examine owner-feedback patterns
We use recent critical and positive feedback to identify repeated themes such as fit, noise, battery behavior, cleaning difficulty or durability. A single review is not treated as proof.
5. Explain fit and limitations
Each recommendation should state who it suits, who should avoid it and what to verify before buying. We do not publish fabricated star ratings or aggregate scores.
Updates and corrections
Dates change only after a meaningful review. Product availability and specifications can change; readers should confirm the exact model and seller. Corrections are handled under our corrections policy.
Commercial independence
Affiliate eligibility does not determine our criteria. We may earn a commission from qualifying purchases, but brands cannot buy a favorable conclusion through an affiliate link.
