Philips SonicareDiamondClean Smart 9300 Electric Toothbrush, Sonic Toothbrush with App, Pressure Sensor, Brush Head Detection, 4 Brushing Modes and 3 Intensity Levels, Pink, Model HX9903/25

Cleans my teeth the best they've ever been. Not to noisy and easy to use. Great battery life and easy to travel with the case. No travel charger though. Love the app as well.

The Philips Sonicare DiamondClean Smart 9300 is a game-changer for oral hygiene. Its powerful sonic technology leaves teeth feeling professionally cleaned, while the smart sensors and app provide real-time feedback to improve brushing technique. The four customizable modes cater to every need, and the sleek design with a long-lasting battery adds to its premium appeal.Though an investment, it’s worth every penny for the visible improvements in teeth whiteness and gum health. If you’re serious about oral care, this toothbrush is a must-have. Highly recommended!

This is my first Phillips toothbrush, and I’m really enjoying it. While it is quite pricey, the payout is in minimizing issues at the dentist’s chair. I really appreciate that the app helps manage time spent in each area of the mouth, pressure, and scrubbing. It also enables you to flag problem areas requiring additional attention, reminding you to take extra care there. After reading some of the comments regarding concerns with charging via a cup, I was also concerned regarding how this may look. That said, I was surprised to see that there is an alternative option for a separate charging stand which is smaller in size and enables the toothbrush to stand upright. I prefer this option, and think it looks very clean and organized. I will second that the travel case does not charge the toothbrush itself. However, I consider this an extra luxury (an electric of toothbrush of this size is NOT one I would have ever considered “travel size” in the first place - a bit of clunkiness should be expected). I would be just as satisfied to pack the charger separately or temporarily opt for a non-electric toothbrush for lengthy travel. All in all, I’m very satisfied with the quality of this toothbrush.

I love this toothbrush it has sensitivity options

The Philips Sonicare DiamondClean Smart 9300 is less of a toothbrush and more of a high-maintenance diva that thinks it's auditioning for a role in a sci-fi movie. While it promises to revolutionize your oral hygiene, it often feels like you're babysitting a gadget that’s way too full of itself.Design and Features: Let’s start with the app. Yes, this toothbrush has an app. Because apparently, brushing your teeth now requires Wi-Fi and a degree in computer science. The app nags you like a helicopter parent, pointing out every spot you missed with the enthusiasm of a dentist who’s just discovered plaque for the first time. And the 3D mouth map? It’s like Google Maps for your teeth, except it’s constantly recalculating because you dared to brush in a way it didn’t approve of.Performance: The pressure sensor is supposed to protect your gums, but it’s so sensitive that it flashes red if you so much as think about brushing with enthusiasm. It’s like having a toothbrush that’s afraid of commitment. And the four brushing modes? Let’s be honest, most of us just want clean teeth, not a menu of options that make us feel like we’re programming a rocket launch.Battery Life: The battery life is decent, but the charging glass is where things get weird. Yes, you heard that right—a charging glass. It’s like the toothbrush is trying to be a fancy cocktail at a high-end bar. Except instead of sipping a martini, you’re awkwardly trying to figure out if the brush is actually charging or just mocking you with its blinking lights.Build Quality: For a toothbrush that costs as much as a small appliance, the build quality is surprisingly underwhelming. The brush heads wear out faster than you’d expect, and replacements are priced like they’re made of gold. The whole thing feels like a subscription service you didn’t sign up for.Verdict: The Philips Sonicare DiamondClean Smart 9300 is the toothbrush equivalent of a midlife crisis. It’s packed with features you didn’t ask for, demands constant attention, and leaves you wondering if you’re the problem. If you’re looking for a simple, effective toothbrush, this isn’t it. But if you’ve ever wanted to feel judged by your dental hygiene routine, this might just be the gadget for you.

It's very clean and comfortable, and it's also convenient to carry when going out. I recommend buying it.

I have been a sonicare user for almost 10 years. The quality of the product is amazing and if there is ever an issue with the product, their customer service is outstanding. So I am not a twice a day, or even regularly floss and my dentist is always amazed at how little to no build up I have on my teeth and never have any dental issues. The different cleaning modes is a great option and having the ability to change the vibration intensity. Yes, the price may seem a bit high, but to have healthy teeth and gums and never need expensive dental work, I would say it is worth the cost.

Excellent toothbrush, but it would be great if they sold a version with the same brush speed and power but without all the tech features, which I never use. I’m not using an app with a darn toothbrush. The heads are also expensive, and it has a feature making aftermarket heads hard to use. This is very much not appreciated.But it does a fantastic job cleaning teeth, which is what I want. Way better than my old Oral B.
