BuyOQ is an independent project run by Mustafa Bilgic, a solo operator based in Adıyaman, Türkiye. We don't sell products, we don't take payment for recommendations, and our guides link only to neutral searches — never to a single "best" product we were paid to push. Where we mention reputable concepts from organisations like Consumer Reports, the U.S. Federal Trade Commission and Energy Star, we do so to point you to trustworthy ideas, not to imply endorsement.
