Philips Sonicare DiamondClean Smart 9750 Rechargeable Electric Power Toothbrush, Lunar Blue, HX9954/56

Best toothbrush I’ve purchased to date. I had an old basic Sonicare tooth brush for over 7 years and while it still worked I decided it was time for a replacement. The app integration with the toothbrush is top notch. First time brushing with the new brush left my teeth feeling cleaner than my old brush would. The different power levels and modes are great if my teeth are being sensitive. The travel case will definitely come in handy for work and pleasure trips.

First day of use, I am very impressed with the product. App could use a little work with the user interface but the toothbrush itself and all the accessories are fantastic and perform as advertised. I got it on sale and am very pleased with my purchase. My wife has the 5700 model and likes it alot too but without app integration its harder to know when you are lacking in an area of the mouth. I strongly recommend this product for anyone that wants a great toothbrush with guidance on ways to improve my oral hygiene.

Incredible. Nothing is close to this toothbrush. I have had several levels of Sonicare toothbrushes from the entry level, several different mid levels, and the level just below this (which I loved but dropped it and broke it). I have had Oran-B’s top level and it cannot to this one. Your teeth feel perfect after brushing every time. The drawback to the toothbrush is that it costs as much as a car payment.

This was the first electric toothbrush I've owned and I've been really happy with it. It looks cool, it's comfortable, it works well, and it leaves your teeth feeling really clean. The battery lasts quite a while between charges. The longest I've gone without charging it was 8 days and it was still going strong. After three years and two months the wiggly bit went all floppy. I can hear something inside of it is loose when I shake it a little. Given the price, I was a little disappointed that it didn't last longer. I called customer support and they agreed to replace it once even though it was out of warranty. As long as the second one lasts just as long, I will feel like I've gotten my money's worth out of it and this thing will retain it's 5-star review from me. As for now, I am very happy with this purchase and would recommend it to anyone.

The mechanism that transmits vibration to the brush head fails. The brush head rattles but does not vibrate effectively, making this no better than regular old toothbrush that costs $330. This is my second of this model. The first one lasted 3 years. The second lasted 3 months. I used Perplexity AI to search for customer complaints. Here it is: Common concerns reported by owners of the HX9954 model include moisture infiltration and seal deterioration, which can allow water to reach the internal electronics and battery contacts over time. This water exposure may lead to issues such as corrosion on the circuit board, lower-than-expected battery voltage, or complete device failure if not addressed promptly. Some users have also experienced a loose screw within the handle’s oscillator mechanism, causing excessive noise or vibrations until the screw is tightened again. Aside from these mechanical problems, some have noted battery-related issues, such as limited charging capacity or sudden drops in voltage, which can result from moisture reaching key components or from impacts that break solder connections on the battery terminals. If problems arise during the warranty period, replacement handles or upgraded models are sometimes offered, but customers have reported inconsistent experiences with manufacturer support or lengthy claims processes.

Few years ago I finally made the switch to electric toothbrushes (not including the brief experience I had twenty years ago with an Oral-B). Previously I had a high end Oral-B electric toothbrush. Then last year I upgraded to a mid-grade (4000 series) Philips Sonicare cleaning brush (that one cleaned at 7x normal brushing compared to this 9750 which touts 20x). I've been a fan of ultrasonic frequencies for cleaning in general because I know what it can do in all sorts of industries. So I was excited to have my Philips sonicare 4000 series brush I got for $10 (Amazon Returns deal). I found that toothbrush more effective than my Oral-B and enjoyed it for quite a while. But then I saw this 9750 on amazon on sale for a REALLY good price (under $200) and knew I had to have it. I placed a pre-order and patiently waited for my new brush. First impressions were "wow", I'm impressed. The box presentation was very befitting for a product of this quality. I really like the glass cup and charging stand as well as the styling of the brush itself. I was a little disappointed to see that the toothbrush holder is made from clear plastic and not glass (I was kinda hoping it would be glass). But overall from an aesthetics point of view, it's a nice brush (I ordered the dark blue/rose-gold color scheme and it looks GREAT). My experience with the brush is spectacular. It is VERY aggressive with the ultrasonic frequencies. I can absolutely feel a difference in the cleaning capabilities of this brush over my cheaper mid-grade Sonicare 4000-series model. For fun I've even tried the Clean+ mode and WOW that was even more aggressive - my eyes felt like they were vibrating from the force! Certainly don't need to use Clean+ on a regular basis, but it was fun and my teeth certainly felt clean! I also really like that the brush automatically identifies when the tongue cleaner is installed (still getting used to that function). It's a cool feature. I still haven't tried the bluetooth functionality and the smart app yet. But so far I'm really impressed. For under $200, it's worth the investment. At $300+ I'd really think twice about the brush (it's good, but I bet you could find something nearly as strong cheaper model sonicare like the 7000 series or 8000 series which would work nearly as well) But like I said, if it's on sale then it's absolutely worth the price!
