BreathEaseX's stated 60-day guarantee, and how the refund process works.

Every order is covered by a stated 60-day money-back guarantee.
Contact official support within 60 days of purchase to request a Return Merchandise Authorization (RMA) number. Include that number with your returned product and provide tracking once shipped. Return shipping is generally at the customer's expense, and products should be in good physical condition with original packaging.
Only through the official website. The brand states the products are not sold through Amazon, retail stores, or third-party marketplaces, and purchases elsewhere are not covered by the guarantee.
