Questions about a guide, a correction to a spec we've listed, or a partnership inquiry — we'd like to hear it.

Email us at hello@rayledger-site.pages.dev. We aim to reply within a few business days.

Before you write

• Corrections: include the page URL and what you believe is wrong, ideally with a link to the manufacturer's published spec.
• Medical questions: we can't give health advice. Talk to your doctor about whether a light or heat device is appropriate for you.
• Partnerships: tell us about your product and your affiliate program terms. Note that commissions never buy placement — see our methodology.
