    This toothbrush really changed my life. It's amazing to think that a simple piece of technology could have drastic effects, but it's true. My gums are healthier and teeth are cleaner without a doubt.

    This toothbrush has 3 levels of power and if you want a gentle clean you can use level 1. It has the same levels of type of cleaning as the older models of the toothbrush. It is a great toothbrush.

    Great toothbrush; smart features aren't worth it

    DiamondClean brush handle has always been a fantastic product. Still is... but most of the smart features are, in my opinion, not at all useful after the novelty wears off. I'd try to find the older model DiamondClean 9000 and pick that up for a lower price. If price doesn't matter, then you're looking at a darn good product.

    I bought it to help with my bleeding gums. After one week of use, I've noticed my gums don't bleed as much. It also removes plaque very well. App is ok. Dont care for it. Toothbrush itself is well worth it.

    Case does NOT recharge the toothbrush

    Don’t buy if you’re wanting it to travel with. The case that comes with it only carries the toothbrush and a brush. You’ll have to schlep along the glass charger in order to charge it despite the fact the manual shows the bottom of the case opening. It does not. I wish I had discovered this before it was too late to return it. If you want the rechargeable case you have to buy the more expensive model. No thanks. I’ll manually brush my teeth from now on.

      Hi there,

      thank you for sharing your feedback. We're sorry to hear that you're disappointed with the travel case of your DiamondClean 9300 Series. Indeed, the travel case for this model is only designed to hygienically store the brush handle and brush head when you're on the go. As of this moment, charging on the go is only available for the DiamondClean 9700 series. We apologize if this was perhaps unclear in the advertisment. We will take note of your feedback, however, to improve our products and services in the future.

      If you have any questions or concerns in the future, please feel free to get in touch via social media. We’re available 24/7 on Facebook (https://bit.ly/3yBQ1qb) and Twitter (@PhilipsCare). Alternatively, you can reach out to us via the contact page on our website. One of our colleagues will then try their best to help you further.

      Kind regards,
