Breaks easily
I’ve been through 3 of these toothbrushes. The pin that holds the head on the base of the toothbrush gets loose with time so I’ve had to replace the toothbrush multiple times. With such an expensive toothbrush, you’d think it would be more durable.

Great Toothbrush
When used with the Sonicare app, you get a complete picture of how well you are brushing. Love the indication of applying too much pressure and the degree of teeth cleanliness. The handle should have had a flat surface opposite the brush head so that the handle would not easily roll over when set down on the bathroom counter.

Good brush, broke quickly
I love the brush. It does a very good job cleaning my teeth and keeping my gums healthier. It keeps a charge well, too. The reason for the lower rating, however, is because it broke after a year of use. The bit where the toothbrush attaches became wiggly which made the brush loud and nearly unusable.

Great but gimmicky
This brush is still a bit aggressive but I am getting used to it. I just hope it will not cause abrasion lesions on my teeth at the gumline. I feel like the mechanisms on the brush could be simplified. There are different levels of intensity labeled in a way that I have no idea how the levels are different one from another. I also feel like Phillips caters too much to public opinion by labeling brush heads as "medium" when they aren't and medium brush heads should never be used. Just be honest with consumers relabeling something to give us what you think we want.

Just moved from a manual brush. Haven't noticed a big change.

A toothbrush supports Periodontal Disaease
The DiamondClean Smart 9300 has truly impressed me with its powerful cleaning performance. Its C3 replacement brush head removes plaque effectively and leaves no residue on my teeth. The adjustable cleaning modes are well designed and easy to use, making daily brushing simple and comfortable. Because I have been diagnosed with periodontal disease, this electric toothbrush has been a real benefit to my oral‑health routine. I highly recommend the DiamondClean Smart 9300 for anyone managing periodontal disease and seeking a deeper, more effective clean.

Designed to fail IMHO
In my opinion: Designed and engineered to fail. There is an metal angle that transmits power from the oscillating magnet to the brush head. This part is designed to fail due to metal fatigue. I have had a number of Sonicare toothbrushes fail (more than half a dozen) and this is always the failure point. Symptom is good vibration but vibration not making it through the brush head. Always outside the warranty period so Phillips Corp. will be very happy....
