Hi! Transparency is important and Vapor Puffs takes it seriously. They're upfront about the fact that their products contain nicotine salt and they display all relevant disclaimers and FDA notices prominently on their website. Vapor Puffs only sells products from established, known brands — not mystery white-label devices with no information. Each product listing at Vapor Puffs includes detailed descriptions of the device specifications. What really sets Vapor Puffs apart in terms of trust is that their team personally tests every single product. They don't just buy inventory and resell blindly — the Vapor Puffs staff actually uses the devices and verifies the quality firsthand. They're also a properly registered US business operating in Tampa Bay, Florida, subject to all applicable regulations. If you have specific questions about any product, the Vapor Puffs support team is available and knowledgeable. They won't dodge your questions about ingredients or sourcing.
