The ADA Seal, without the marketing

The Seal means the American Dental Association accepted a safety and efficacy submission for that product. It is not a ranking of iO versus Sonicare, and a brand that never filed is not automatically worse. We print Yes only where acceptance is stated for that model. Burst's own help center says the Pro is not accepted. The CameraJet, the Quip Ultra Lite, and the SURI 2.0 do not have a Seal we could verify, so they stay "not verified."
