A little help, every step of the way.

Check the inbox and spam folder for the email address used at checkout. If you still cannot find the coupon, contact us below and choose “Missing coupon or resend.” Include your order number if you have it. We can check the reservation and help you recover its coupon.

Yes. Contact us using the form below and choose “Email correction.” Include the order number and tell us that the checkout email needs correcting. Customer care will verify the request before changing where reservation information is sent. Do not include payment-card details.

Adults may buy multiple reservations. Each successfully paid US$0.99 reservation provides a separate US$40 coupon for one eligible toothbrush. You may gift a coupon to another adult. Reservation coupons cannot be stacked on the same toothbrush or combined with other discount codes or promotions; the promised free shipping still applies.

The reservation is ordinarily nonrefundable for a change of mind. You may request a refund during the seven days between price reveal and launch if you decline the revealed price. Alaska or Hawaii customers may receive a refund if they decline the shipping quote at final purchase. We also refund the reservation if iGrono cancels the launch or cannot provide the promised coupon benefit. A reservation refund cancels its unused coupon. See the Refund, Return and Warranty Policy for the full terms.

Shipping timing will be announced when confirmed. Your reservation has no physical shipment. The final toothbrush purchase includes free shipping to the contiguous 48 states and Washington, DC. Alaska and Hawaii shipping is quoted at the final purchase.

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 refund-submission period, not the approval-review period.

1-Year Limited Manufacturer Warranty. Replace, not repair.

Manufacturing defects in the toothbrush main body and magnetic charging dock are covered for one year from delivery. The supplied cable is not covered by this voluntary warranty.

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 using the original website order proof. The same coverage and original one-year-from-delivery expiry apply.

For a valid 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.

Brush heads and toothpaste cartridges: For verified manufacturing or delivery defects, we replace the affected item free of charge or refund it if a replacement is unavailable. Normal bristle wear and toothpaste used up through ordinary use are not covered as quality defects. This separate remedy does not extend the one-year main body and dock warranty to consumables. Your applicable rights remain.

For a refund of a defective standard-kit component, we use its disclosed share of the actual kit price you paid, with discounts allocated proportionally. We will show the component allocation before you purchase the toothbrush. An eligible full-kit refund remains the full product amount actually paid.

The seller and warrantor is HONGKONG FENGGAN TECHNOLOGY GROUP LIMITED.

You may request a change-of-mind return within 30 calendar days from delivery for unopened, unused products. These returns must include the complete kit, all supplied accessories and the original product packaging; the outer shipping carton is optional. For an eligible change-of-mind return, we refund the product amount actually paid, with no restocking fee.

For a change-of-mind return, a separately paid original delivery charge is nonrefundable after delivery has been provided. If your original shipping was free, we do not deduct an outbound shipping charge. Defects, incorrect deliveries and company cancellations are handled separately.

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

For support or a return request, email seller@igrono.com.

We investigate with the carrier if a correctly addressed shipment is reported lost or delivered to the wrong location. A carrier delivery scan alone does not justify rejecting a claim.

For confirmed loss or misdelivery, we provide a free replacement if available. Otherwise, we refund the amount actually paid for the undelivered item plus its attributable separately paid delivery charge.

If our investigation confirms that a parcel was lost solely because you supplied an incorrect address, we review the case individually; a free replacement or refund is not automatic. We help correct addresses before dispatch when possible and agree any reshipping charge with you before resending. This does not limit remedies for company or carrier errors, rights regarding recovered goods, or your applicable legal rights.

If our investigation confirms correct delivery followed by theft, we review the case individually; a free replacement or refund is not automatic. A carrier delivery scan alone does not prove correct delivery or theft, or justify rejecting a claim. The remedies for confirmed carrier loss or misdelivery and your applicable rights remain unchanged.

You may cancel a final toothbrush order if we can still stop dispatch. We then refund the product amount actually paid plus any separately paid delivery charge for delivery not provided.

If dispatch cannot be stopped, our return policy and applicable rights apply. Reservation payments follow their separate cancellation and refund terms.
