Ranking: Renvo Score first, then price. Products without enough evidence for a score are listed after scored ones, by price. Commission never affects order, and sponsorships cannot buy higher rankings (§ 5b UWG, ranking factors).

What the claims are worth

Brand statements (e.g. "low EMF", irradiance figures) are marketing claims unless an independent measurement is linked. We make no health claims and don't test products hands-on. See how we grade evidence.
