"...The battery life is great, i can go a day or two without charging and use twice a day with no issue, then again, to charge it I just drop it back..." Read more

"...The last one concerned me because of the short battery life. Skeptical to spend the money on the Smart 9300...." Read more

I have been using Sonicare for over thirty years. This is my third one as the batteries are not replaceable. My last two were white but this one is black. It was slightly cheaper than the white, perhaps the black is not selling as well. The 9300 has many features so you can customize the experience. When it is time for a new brush head (about 3 months) I would recommend an O E M replacement. The aftermarket ones are a lot less money but most are of poor quality.

Reviewed in India on January 19, 2022
Spent almost 40k on this worthless product which came with a Chinese Flat 2 pin.
Amazon support is worse, they would not escalate the issue and offer a simple resolution - can you buy an adapter?
I mean if I bought an apple or samsung which are also made in china, would they come with chinese adapters?
The seller does not mention that this item comes with a chinese adapter and is misselling the item.
What good is an electric toothbrush when it wont charge?
