Philips Sonicare DiamondClean Smart 9300

My teeth are feeling so amazing after just one month of using it!

I love the different settings on this toothbrush. The deep clean is my favorite.

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.

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.

Broke really fast! The brush stopped working they recommended I cleaned it which I had already done. Still unable to charge. Waste of $300!

I have used a different Sonicare toothbrush model for about five years and decided to upgrade to the #9300 Diamond Clean model. I am very pleased and wish I had upgraded sooner! This Sonicare Model 9300 with the accompanying App work very well together. Through the App, I have been able to correct many of my old brushing habits where I was not brushing my teeth properly and holding my toothbrush correctly. The App and Sonicare working together is Amaxing! I highly recommend the Model 9300 Diamond Clean!

Love the toothbrush, hope that it lasts longer than my last one. Bert easy to use and the promos help me do a better job brushing my teeth

I wrote a review earlier after experiencing a quality control issue with this toothbrush. The metal rod, to which the brush attaches to the handle, had become very loose to the point where the toothbrush was barely usable. Years ago, a top business executive once told me that the company for which I worked at the time would, at some point, mess up, because it happens to all companies. What mattered to him was how the company would respond when it happened. I mention this because Philips went over and above to resolve my problem, acting promptly in a way that was both fair and generous. In fairness to them, it's only right that I recognize such wonderful customer customer by posting a second review, this time awarding five stars. They deserve it.

It has been great in cleaning my teeth, whitening my teeth and also overall health of my teeth. Well worth the money for the device

Love this brush and so does my dental hygienist. Best visits to the dentist since this purchase
