Zero Testing for NRR
This company is a Chinese company and ships untested products. Ask them for any published ANSI S3.19 / EPA NRR lab. They dont exsist. They warranty claim in small letters is only if you dont open or use the product. In other words if you test it in anyway they wont take it back. Look them up on Reddit 100s of complaints of the same thing. All positive reviews are fake and they try and trash other companies to get clicks.

Hey Don, We must admit, it is rather difficult to investigate a customer experience when we cannot find any record of you contacting our support team or providing the order details needed to verify a purchase. We have checked our available records for any previous communication regarding the concerns in your review, but we have been unable to locate one. We also haven't received the information needed to establish whether you have personally purchased or tested our products. That makes it difficult to understand how you reached such definitive conclusions about our product testing, warranty conditions, and customer experience. We welcome honest feedback and legitimate questions about our products, testing standards, and policies. However, there is a difference between sharing a firsthand experience and making broad accusations without providing verifiable details. If you have personally purchased our product and encountered these issues, we would genuinely appreciate the opportunity to review your specific concerns. We also would have welcomed the chance to address your questions directly before seeing these allegations posted publicly. After all, our support team cannot investigate an issue we haven't been given the opportunity to review. If you have an order with Ravine, please contact us at [email protected] with your order details so we can look into the matter properly. We are happy to address substantiated concerns, but we believe fairness and accuracy should apply to reviews just as much as they should to businesses. Regards, Amanda Social Media Team
