What to send us

• Certification corrections. If a certification record we've cited is wrong or out of date, tell us the model number and the listing — we'll verify and correct it.
• Review suggestions. Tell us which systems you'd like us to assess against the certification listings.
• Business inquiries. Affiliate or advertising questions — note that neither buys placement or editorial input (our disclosure).

We read everything but can't reply to every message. Corrections backed by a certifier listing get priority.
