A precision CNC-machined shaft delivers Bass-style sweeping plus vibration, rather than ordinary vibration alone. The base frequency is specifically tuned for children’s primary teeth and delicate gums, and the motion path follows the principles of the Bass brushing technique.
A built-in high-precision gyroscope tracks brushing orientation in real time.
Only time spent in a valid brushing orientation counts toward the star rating on the brush. App goals and rewards help make progress motivating.
Kids try harder when there’s something to work toward.
That’s why the iGrono app lets parents set a brushing goal and choose the reward. Every session is tracked automatically, so progress is easy to follow day by day. When the goal is reached, the reward unlocks—turning a daily routine into a milestone they’re proud to hit.
Designed for ages 3+
Pumping pressure precisely triggers valve closure. When the pressure is removed, elastic action immediately seals it shut, preventing toothpaste backflow. Every dispense is clean and controlled, for more hygienic long-term use.

Peristaltic delivery uses rollers to repeatedly compress flexible tubing, propelling toothpaste from outside the tube wall. No moving mechanical parts directly contact the toothpaste; only the tube’s inner wall touches it, greatly reducing trapped residue and buildup.
A built-in high-precision gyroscope tracks brushing orientation in real time. Unlike ordinary brushes that simply time a session, it counts only effective brushing time with valid orientation. That time determines the brush’s star rating; paired with app goals for motivation, it recognizes whether children actually brush attentively, rather than merely leave the brush running for two minutes.
iGrono is designed for children ages 3 and older.
The main body comes in Purple, Pink and Beige.
Head A is firmer, for cleaning, suggested for permanent teeth. Head B is softer, for gum care, suggested for primary or mixed dentition.

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.
Also included: an 80 cm braided Type-C cable and two protective covers.
USB-C power adapter (5 V ⎓ 1 A) not included.
