Philips Sonicare DiamondClean Smart 9300 Rechargeable Electric Power Toothbrush, Grey, HX9903/41

I had a very old Sonicare toothbrush I’ve been using for probably 10 years. It finally came time to replace it. After looking at the various Sonicare models I ended up going with this model because of the four different cleaning modes and because of Bluetooth connectivity. Since I was already using a Sonicare I figured my new toothbrush would brush like my last one. I was surprised by how much better my mouth feels after brushing with this toothbrush, especially after using the deep gum cleaning mode. I imagine Sonicare’s technology has changed since I purchased my toothbrush about 10 years ago and their is a noticeable improvement. I don’t use the app all the time but used it for the first week. It was great at telling me if I was pressing too hard, moving too fast, or missing sections. It really helped me learn to brush better. You don’t have to use the app every time you brush. The toothbrush remembers your brushing sessions and when you do open the app will sync your sessions with the app. I’m unsure how many sessions it will save. After syncing, you can then check your progress and see how you’ve been doing. The brush and the app are a good combo at helping you brush better.

I bought this as a replacement to the one I purchased back in 2015! It lasted a long time but after a hard drop on granite it stopped working. Looked at the cheaper models but decided to go for the more expensive version considering how long the last one lasted. I love it, it gets your teeth really clean.

UPDATE! I called customer service to explain what happened and because it is technically still under warranty they are sending me a new one with a box to send my old one back to them!!! AMAZING!!!! I thought i would just have to eat the 250.00 but YAY!!! GREAT CUSTOMER SERVICE AND MAJOR PROPS FOR STANDING BY THEIR PRODUCT!!!I think this is a great toothbrush but exactly 1 year its completely dead.

I like this toothbrush better than the spinning ones. This one is a bit pricey, but it's good quality and worth the price.

We have been using sonicare toothbrushes for years. Seriously, a better electric toothbrush does not exist. We have owned Diamond cleans, Healthy Whites and various other models. We have also have had Oral B electric toothbrushes given to us when we each did Invisalign. There is no comparison.Anyway, I currently have the grey Diamond clean (purchased 7/30/2022), my husband has the black and ours kids have different sonicare models that they love and got for Christmas.***Stuck power button tip. I recently noticed that my power button to turn on the toothbrush was becoming harder to press. After each use I rinse and dry the handle. Even though I do that, some tooth paste was building up around the power button and it was becoming impossible to use anymore. The button was stuck in a depressed position making it harder to turn on. I did a quick search and saw a tip on ifixit. Run hot water from the faucet over the power button and using a manual toothbrush (we have tons of them from doing regular dental check ups) gently brush that button a few times. Press the button, it’s like magic.We do not use the app at all so I am not rating that. Amazing brushes, long battery life, clean teeth. Use this and get amazing results at your dental visits.

Excellent, as expected

I know sonicare is said to be the best quality product for electronic toothbrush and is recommended by the dentists.I have been using it over a decade, but I can't count anymore how many times I "re"purchase the body or charger. Almost every 2 years, it does not work at all. Big garbage. I recommended to friends and family, and heard the same story. Is there any decent electronic products having the decent lifespan as the real good quality product with this price ? I remember they did not have the good customer service long time ago and I gave up for the first time it was broken, when the $200 electronic brush was not functioning in the first year. And again, this was not working at all after a year and a half. I did not even try to contact to the customer service but now we all have the difficult time to goto the dentist so I just contacted customer service at Philips. I had really an unpleasant experience like other reviews. I wish I read it and should not religiously keep buying Philips products over a decade.

I was hesitant to spend the money of this but I’ll say this is way better than the oral b toothbrush. My teeth feel so much cleaner after using this!
