What this checklist verifies
This resource is designed for B2B buyers who need to qualify a visual ear cleaner OEM supplier before asking for price. It turns the sourcing conversation toward evidence rather than broad factory claims.
- Ask for fixed-distance image samples instead of accepting a resolution claim alone.
- Request WiFi pairing and reconnection records for app-connected models.
- Check whether battery, waterproof and OQC claims have dated factory logs.
- Map each certificate to the exact SKU, market and shipment BOM.
