Very happy with my new DiamondClean toothbrush
[This review was collected as part of a promotion.] I really like the new DiamondClean toothbrush. I have used SonicCare toothbrushes for years and the DiamondCare is a step above those. I love the little glass battery as opposed to the SonicCare battery holders.

Broke after a few months
[This review was collected as part of a promotion.] This device broke within the first few months of ownership. Phillips then sent me what appeared to be a referbished device that wouldn’t even charge and refused to send me a new one. I would NOT recommend buying this product.

Not perfect but a good toothbrush
It's good don't get me wrong but I find the heads are very large so hard to reach the back of your mouth,
Considering the price I would expect a bit more from the toothbrush although it does clean very well once you get used to just how powerful the vibration is, it would be nice if there was a smaller possibly round or oval shaped head available (like my previous oral b) as that seemed a much more convenient size for harder to reach areas. The app is more of a gimmick that I used 2/3 times at the beginning but not much after a month or 2 and it doesn't always detect the correct position you are at, the area timer also doesn't really give enough time on each area to get all around the teeth,

Thank you for sharing your feedback with us. If the device doesn't always detect the correct position, you should hold the brush at a 45o angle to your gum line. Also, the app should be updated.
If this doesn't improve the device or if you have any further questions please get in touch with us via Social Media. We' re available on Facebook (@Philips) or X (@PhilipsCare). Don't worry if you don't use Social Media. You can also reach out to us via our contact page (www.Philips.com/contact).
Hope to speak to you soon.

Not as expected
[This review was collected as part of a promotion.] Brush is too strong on tooth. It does clean your teeth, but it’s too much on the gums.
philips.com response
Hi there,
Thank you for sharing your review. We’re sorry to hear that you feel your Philips Sonicare DiamondClean Smart 9300 is too strong on the teeth.
We would like to inform you that your toothbrush gives you the option to choose between 3 different intensity levels: low, medium, and high. Based on the brush head you attach, the intensity will be selected automatically. If you wish to change to a different intensity, you can do so by pressing the mode/intensity button while brushing. For optimal results, it is recommended to use the automatically selected intensity. The intensity cannot be changed as long as the handle is powered off or paused.
If these tips do not help or if you need further assistance, please reach out to us via social media. We are available on Facebook (@Philips) and X (@PhilipsCare). If you do not use social media, you can also reach us through the contact page: www.Philips.com/contact.
Kind regards,
Philips Consumer Care

One really bad failure
[This review was collected as part of a promotion.] I like the brush a lot. BUT... the fact that the app can't pair with more than one toothbrush is ridiculous. We have two homes. Your app makes me repair every time, and then you lose all your stats and counting down to replacement of the toothbrush. Because of that hassle, I've stopped using the app (just not worth having to repair twice a week), so I'm not getting the benefit of the app telling me where I'm missing brushing, etc. I actually bought 2 of those counters bus drivers use to count riders -- I am using those to count to 180 on each toothbrush. If you fixed the app, this toothbrush would be perfect.

Love this toothbrush!
I've been using Sonicare/InterPlak for decades. This DiamondClean Smart toothbrush lasted 5 years! Unfortunately, I had to order a new one because the spindle became loose and vibrated terribly. It was just a matter of time before it came off completely. I definitely feel I got my money's worth since it lasted 5 years. Just ordered my replacement.
