Refund, Return and Warranty Policy

Effective October 17, 2026, when this offer is published. These terms apply to new reservations placed under this offer. Existing reservations and completed purchases retain the terms accepted when they were purchased. The physical-product terms below apply to toothbrush purchases made under this offer when regular sales open.

The seller and warrantor is HONGKONG FENGGAN TECHNOLOGY GROUP LIMITED. For support, cancellation or a return request, email seller@igrono.com.

US$0.99 reservation refunds

The US$0.99 reservation payment is separate from the toothbrush purchase. It is ordinarily nonrefundable if you change your mind, with these exceptions:

• If you decline the revealed toothbrush price, you may request a reservation refund during the seven days between price reveal and the actual launch. Your request must be made during that window; the refund does not have to be completed before launch.
• For delivery to Alaska or Hawaii, shipping is quoted at the final toothbrush purchase. If you decline that quote, we refund the US$0.99 reservation payment.
• We refund the reservation payment if iGrono cancels the launch or cannot provide the promised coupon benefit.

A reservation refund cancels its associated unused US$40 coupon. It does not reverse a completed toothbrush purchase or change the terms already accepted for that purchase.

Canceling a final toothbrush order

You may cancel a final toothbrush order if we can still stop dispatch. We then refund the product amount actually paid and any separately paid delivery charge for delivery not provided. If dispatch cannot be stopped, the return policy and your applicable rights remain available. The separate reservation payment follows the reservation-refund rules above.

Unopened, unused returns

You may request a change-of-mind return within 30 calendar days from delivery for an unopened, unused product. A kit return must include the complete kit, all supplied accessories and the original product packaging. The outer shipping carton is optional. These packaging requirements apply to change-of-mind returns, not to defect or incorrect-delivery claims.

For an eligible change-of-mind return, we refund the product amount actually paid, with no restocking fee. You pay the disclosed return-shipping cost. An original delivery charge that you actually paid is nonrefundable after that delivery service has been provided. If original shipping was free, we do not deduct an outbound shipping charge. Defects, incorrect deliveries and company cancellations are handled separately.

Requesting and sending a return

Email seller@igrono.com to request a return and receive return authorization and usable shipping instructions. Hand the approved return to the carrier within 14 calendar days after you receive both the authorization and usable instructions. This is the carrier-handoff deadline, not a deadline for the parcel to arrive at the return destination.

iGrono pays return shipping for verified manufacturing defects or fulfillment errors. You pay the disclosed return-shipping cost for a change-of-mind return.

Wrong, missing or damaged items

Please report wrong, missing or damaged items within 30 calendar days of delivery. We review later reports individually rather than automatically rejecting them. Defects and incorrect deliveries retain their separate remedies and your applicable rights.

For lost or misdelivered shipments, customer-supplied address errors and theft after correct delivery, see our Shipping Policy.

One-year limited manufacturer warranty

Manufacturing defects in the toothbrush main body and magnetic charging dock are covered for one year from the original delivery date. The supplied cable is not included in this voluntary warranty. This does not remove your applicable rights concerning defective or incorrectly delivered goods.

For a valid warranty claim, we provide a new replacement covered until the original warranty's end date. If a replacement is unavailable, we refund the amount actually paid for the affected item.

If a toothbrush purchased on this website is given as a gift, an adult recipient, or an adult caring for a child recipient, may claim warranty service using proof of the original website order. The original coverage, delivery date and warranty expiry still apply. Any approved refund goes to the original payment method.

Brush heads, toothpaste cartridges and kit components

For verified manufacturing or delivery defects in brush heads or toothpaste cartridges, we replace the affected item free of charge. If a replacement is unavailable, we refund the affected item. Normal bristle wear and toothpaste used up through ordinary use are not quality defects. This separate remedy does not extend the one-year main body and dock warranty to consumables.

When an approved defect remedy requires a refund for a component of the paid standard kit, we use that component's disclosed share of the actual kit price paid, with discounts allocated proportionally. We will disclose the component allocation before the toothbrush purchase. An eligible full-kit return continues to receive the full product amount actually paid.

How approved refunds are paid

We submit approved refunds to the original payment method within five business days after approval. Your bank or payment provider may take additional time to post the refund. This is the time for submitting an approved refund, not a promise that the funds will appear within five business days or a deadline for approving a claim.

These policies do not limit your applicable legal rights.
