How we review

Every review follows the same steps, so you can judge how much weight to give it.

1. We read the seller's own sales page, terms, guarantee and refund policy, and note every claim.
2. We check those claims against independent public sources, such as U.S. government guidance, and say clearly when we couldn't confirm one.
3. We record prices and package options on the official site, with the date we checked.
4. We write who the product suits, who should skip it, and what it can't do.
5. We review prices and details regularly and update the date on the page when something changes.

Rules we keep

• We tell you on every review that we may earn a commission
• We don't repeat claims we couldn't verify as if they were facts
• We don't use fake reviews, invented testimonials or made-up press mentions
• We don't accept payment to change a verdict

What we don't do

Unless a review says otherwise, we have not lab-tested the product. Our reviews are research-based: they summarize what the seller states, what independent sources say and what you should check before buying.
