AI review summary

The May 31 public sweep did not verify a customer-review platform or product-level review base for Onyx Bio Labs. The vendor site contains a Trustpilot marker, but Trustpilot itself was blocked by bot verification/API access, Reviews.io returned 401, and the Store API showed 0 product reviews across 40 public products. VialVerdict therefore keeps this vendor on Our Rating rather than implying a current external customer-review average.
