Returns

You have 30 days from delivery to request a return.

• Unopened, unused items: return for a full refund of the product price.
• Defective or damaged items: we'll replace or refund at no cost, including return shipping. Email a photo or short video of the problem with your order number.
• Opened, used items that work correctly: because a water flosser is a personal hygiene product, we can't accept used units back unless they are defective.

How to start: email support@dewfloss.shop with your order number. We'll reply with the return address and instructions. Please don't send items back without contacting us first.

Refunds go back to the original payment method within 5–10 business days after we receive the return. Return shipping for change-of-mind returns is paid by the customer.
