Quality Assurance — Try It, Test It, Trust It
Try the product before you order. Watch the inspection during production. Lean on the 24-month warranty after delivery.
One defective unit can cost you $10,000+ — through 1-star reviews, Amazon listing suspensions, FDA complaints, or product liability claims.
That's why we run three layers of risk protection on every order:
- A real product to test before you commit
- Documented inspection during production
- A 24-month warranty after delivery

This isn't marketing copy. It's our SOP for every order we ship.
Yes — encouraged. SGS, Bureau Veritas, Intertek, and TÜV are all welcome. We coordinate the visit and provide all production documentation. For orders over $20,000, we cover the inspector's fees.
Our 24-month warranty kicks in. We need the unit serial number and a brief defect description. We diagnose remotely first; if hardware replacement is needed, a new unit ships from California within 48 hours.
Three reasons:
- Every finished unit goes through 8-24 hours of aging testing — catches 99% of early-life failures
- We use medical-grade components, not consumer-grade
- Final OQC sample of 5-10% of every shipment before sealing the container
For OEM/ODM products under your brand, you'll need your own 510(k) — but our existing clearances dramatically speed up the process. We provide all manufacturing documentation, biocompatibility test results, and predicate device research you need for your submission.
Yes. $5M USD product liability coverage. Certificate of insurance available on request for verified buyers.
