Title: Great toothbrush for managing oral health
Review: 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.

Title: Great, but lasts only 3 years
Review: I’m on my third high-end Sonicare.Pros:Regular dental cleanings used to take forever with lots of comments from my dental hygienist that I had tons of plaque. That is a thing of the past with this brush. It worksCons:I’m on my 3rd one. They don’t last forever. They will break if u drop them on the head. The part the head connects to can become too loose.They work so well I’m ok buying a new one ever 3 years or so.

Title: Do Your Teeth A Favor and Buy This Toothbrush NOW!
Review: Absolutely blown away with this electric toothbrush. I honestly didn’t buy one of these for years because I thought it was being hyped for no reason. I decided to purchase one after learning how much it helped my Dad with his teeth after his lingual nerve was severed during wisdom tooth removal. He told me that his dentist noticed a huge difference in how much plaque was on the left side of his mouth (the side that was damaged due to the nerve sever). I was sold. I have been using this brush for maybe a year and I have not had one cavity since using it. My teeth feel cleaner right after I brush. I can tell a difference and my dentist can too. This toothbrush gets not only my seal of approval but my dentist’s approval too!I should also mention that I enjoy the blue tooth connectivity to the app. It makes sure I brush all sections of my mouth evenly, with not too much pressure or scrubbing. It gives real time feedback as you brush. I found this brush easy to use because of the app. I feel if I didn’t have the direction of the app (at least in the beginning) I would have been confused as I was so used to scrubbing my teeth. The charge lasts well over a week. The cute cup charger is a definite bonus because it looks good on my counter.Overall, I highly recommend this toothbrush. Do your teeth a favor and buy one sooner rather than later.

Title: Best Toothbrush
Review: 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.

Title: Philips Sonicare DiamondClean Smart 9300 Review: A Toothbrush with an Identity Crisis
Review: 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.

Review: I switched to this toothbrush from the well know competitor. The Philips is superior in the overall ease of use. I also feel my teeth are cleaner. Love the cup charger that is an actual glass cup over top of the charger! Being able to quickly dump the toothbrush into the cup to charge without having to align is very convenient. Any drips or residue falls into the cup and it’s a breeze to rinse/clean. The heads are a nice size and softness. I’m very happy. I bought another one for a family member!
