We Review the Category Before the Brand
A product name can hide important differences. We first identify what the product physically does: surface pressure, suction, rolling massage, vibration, heat, electrical stimulation, light exposure, compression, or an electromagnetic field.
Evidence and contraindications are evaluated at that mechanism level before a retail product is considered. Research on acupuncture does not validate an electrical pen. Research on practitioner acupressure does not validate every spike mat. A study of one PEMF protocol does not validate all PEMF mats.
Search Intent and Page Fit
Every article is assigned a primary intent such as commercial investigation, comparison, how-to, safety, or informational. A product card appears only when the page declares a matching product category.
Some high-risk searches intentionally have no direct product match. For example, a page about neuropathy may explain buying risks without presenting one universal winner. Safety context takes priority over forcing a visitor into an affiliate funnel.
Product Information We Track
Our internal product catalog records:
- product name and ASIN;
- physical function and category;
- editorial priority;
- a practical risk level;
- a short safety note;
- the affiliate URL used on the site.
Risk levels such as low, moderate, and higher-caution are editorial shopping labels. They are not medical classifications and do not determine whether a device is safe for a particular person.
What We Compare
Depending on the category, we examine:
- traceable manufacturer and model information;
- intended use and prohibited uses;
- output, intensity, temperature, pressure, wavelength, frequency, or timer controls;
- materials, cleaning, skin contact, fit, and replaceable parts;
- implanted-device, pregnancy, skin, sensation, vascular, and medication warnings;
- warranty, return policy, restocking fees, and customer support;
- whether cited research used the same device and protocol;
- whether advertising language exceeds the available evidence.
Hands-On Testing
We do not imply that a product was personally tested unless the article contains a documented testing record. A product card, Amazon link, or detailed description is not evidence of hands-on use.
When no testing record exists, we rely on traceable specifications, instructions, evidence, safety information, and seller disclosures. We describe that work as comparison or review—not personal testing.
Prices, Ratings, and Availability
Amazon prices, ratings, sellers, and availability can change. We avoid presenting a price or rating as permanent unless it is displayed through an authorized current-data mechanism. Readers should verify the current seller, specifications, return terms, and availability on Amazon before purchase.
Evidence and Regulatory Claims
A mechanism is not the same as a demonstrated consumer benefit. Regulatory registration is not clearance or approval. Device clearance, when relevant and verified, applies only to the exact device and intended use.
Read our Evidence and Citation Policy for the hierarchy of sources and rules for translating research into product language.
Final Publication Checks
Before publication, a page must have required metadata, references, internal links, affiliate disclosure, a matching product category, and no blocked medical wording. It must then receive explicit approval and pass a production build.
After publication, Search Console and affiliate-click data may show that a page needs a clearer title, faster answer, different internal links, or better product fit. We update existing pages before creating near-duplicate articles.
