Verified Buyer Reviews
“I genuinely thought I was brushing for two minutes. The timer proved me wrong on day one. Teeth feel smoother by the end of the first week.”
“Four heads meant the whole family switched at once without buying four brushes. Sensitive mode is soft enough for my mum.”
“One head arrived loose in the box. One WhatsApp message and they shipped a replacement right away — no questions, no proof asked.”

👨👩👧👦 4 Brush Heads In the Box – A family of four can share one handle without sharing a single bristle — or it’s a year of replacements for one person.

What makes it Different?
A manual brush leaves you guessing — how long, how hard, did you get the back ones. The 2-Min Auto Stop Electric Brush removes all three questions: sonic vibrations do the cleaning so you don’t scrub, a pulse moves you every 30 seconds, and it stops itself at two minutes. Four heads and six modes mean the whole house is covered by one handle.
You're Brushingfor 45 Seconds.
Almost nobody actually does two minutes.
Without a timer most people stop around the 45-second mark and genuinely believe they finished. Scrubbing harder feels like it works better — it doesn’t, and over time it wears at the gumline.
42,000 Vibrations.Zero Guessing.
Hold it, guide it, let it work.
- Pulses every 30 seconds to change quadrant
- Stops on its own at exactly two minutes
- Reaches between teeth and along the gumline
Backed by our 14-day Kartzo money-back guarantee!
Four Heads.One Handle.
Brush heads are personal — handles don’t have to be.
A family of four shares one brush without sharing a single bristle. On your own? That’s roughly a year of replacements at the three-month mark dentists suggest.
35 Days.One Charge.
Charge it monthly, not nightly.
- Four hours on USB — over a month of twice-daily brushing
- IPX7 sealed — rinse the whole handle, not just the head
- Leave the cable at home when you travel
Six modes on one button: Sensitive, Gentle, Clean, Whitening, Polish, Massage.
Hear it from a Daily User
I’ve used three electric brushes and the thing that actually changed my routine was the auto shut-off. You stop negotiating with yourself about whether that was two minutes.
Sensitive mode for the first week, then Clean. A month in and my hygienist noticed the difference along the gumline.
FAQs // KARTZO BRUSH
Still Wondering? We've got you covered.
Start on Sensitive mode — it’s the softest setting and made for exactly this. Guide the brush lightly instead of pressing; most brushing sensitivity comes from pressure, not the brush. If you have receding gums or ongoing pain, check with your dentist first.
Every three months, or sooner if the bristles splay out. Four heads are included, so that’s about a year covered for one person.
Yes. The body is IPX7 rated and fully sealed — you can rinse the whole handle under the tap, not just the head.
Up to 35 days of twice-daily, two-minute brushing. Heavier use on the higher modes will bring that down. A full charge takes about four hours over USB.
Sensitive (gentle start), Gentle (tender gums), Clean (deep everyday), Whitening (surface stains), Polish (smooths enamel) and Massage (gum care) — all from one button.
Older children can use it on Sensitive or Gentle with an adult supervising. It isn’t designed for toddlers.
Yes — that’s why four heads are included. Everyone clicks on their own head and picks their own mode. The handle is shared, the bristles never are.
Dispatched within 24 hours with free shipping across India, and tracking sent by SMS and WhatsApp. Delivery typically takes 4–7 business days. Cash on Delivery is available across most serviceable pincodes.

The timer is the whole point
I was definitely brushing for under a minute. The auto shut-off ended that argument on day one.

Teeth feel dentist-clean
That smooth feeling you get after a cleaning, but at home every morning. Genuinely noticeable.

Four heads sold me
Whole family switched at once. Everyone has their own head and their own mode. Great value.
2-Min Auto Stop Electric Brush
Battery is unreal
Charged it once when it arrived and it is still going five weeks later. Took it travelling without the cable.
2-Min Auto Stop Electric Brush
Sensitive mode is genuinely soft
I have receding gums and was nervous. Sensitive is gentle enough that I use it twice daily now.
