I bought this product when my old Sonicare Diamond started to get really loud and just didn't brush as well anymore. Unboxing it was a treat. The packaging, the handle, brushes and charging case all looked really good. The app worked well with the brush and I was loving it. I particularly loved the tongue brush that came with the box.After about three months, the toothbrush went from a nice quiet buzz to extremely loud and the brush function just wasn't doing it's job. I thought, oh no! Not again. So, I contacted Philips through the app and was given the phone number to contact them. The support centre for Australia were extremely good. They asked me a series of questions about the toothbrush and what was happening and assessed that I needed a replacement handle ... MoreI bought this product when my old Sonicare Diamond started to get really loud and just didn't brush as well anymore.

The toothbrush is awesome and does what it says it will do. My gums feel healthy, my teeth look whiter and I'm pretty happy in general with the product. I also trust Philips to replace the handle should anything go wrong again. Fingers crossed.

Been using this brush for 2 months after 20 years of using the only real alternative manufacturer on the market. With this elite Phillips brush, you have to brush for well over 2 mins on max setting to get the feel of clean that 2 mins with a non-Philips brush gives you on a medium setting.The battery on these devices is nothing like reviewed or advertised, mine lasts less than a week brand new. Perhaps due to needing to brush for so long everyday as per my first point.The smart brush head has told me I need to replace it after 5 weeks of usage.I’ve had electrical problems, brush randomly switching off, sometimes after 5 seconds of running. Not being able to switch it off.

Looks good, the hum is better than the sound of Non-Philips toothbrush motors, although I’m not convinced it’s quieter. The travel case is nice and compact. The app is nice if you need that, but becomes almost pointless as you learn how to brush with this style of brush.

Honestly, it's a beautiful toothbrush (I got it in rose gold) so it's pretty on my countertop. I also love that it's thoughtfully designed. The charging base has a frosted plastic cover so it doesn't get wet but doesn't ruin the appeal. The toothbrush is lightweight, and the bottom flashes between two different colors depending on if you are moving around too much or pressing too hard. I also love the buzz to let you know to move on from a section. I also know I'm getting a great clean when I'm using this toothbrush!I love the three strength settings too. I'm still on level 1, which is plenty for me, but I like that it can be controlled as I know other electric toothbrushes don't always allow for that. Even on level 1, sometimes I'll splash a bit and foam quite a ... MoreHonestly, it's a beautiful toothbrush (I got it in rose gold) so it's pretty on my countertop.

I'm happy to adjust knowing I'm getting cleaner teeth in return!I did start with the app, which was cool to see where I might have missed a spot in my teeth, but I've since stopped using it as the toothbrush itself has plenty of features to help guide me in my toothbrushing.It is pricey, but well worth it. I also was able to use my HSA dollars towards it to lessen the pain of the cost!

The best part of this toothbrush is the case and type C charger. The case is compact and beautiful and the magnetic closure is good too although I wish it were a little stronger. The toothbrush itself works great. I would recommend to someone who does NOT change brush modes. I however do change brush modes. You can't do that from the handle of the brush, you must open the app on phone to do so. When you are rushing, that is not feasible. I also thought that this was a smart brush that would change modes based on the brush head being used but to my disappointment, that is not a feature either. I would like a little more weight in the brush handle as it feels like it's going to fall out of my hands quite a bit. It's not slippery, just weightless... feels cheap, ... MoreThe best part of this toothbrush is the case and type C charger.

I would like a little more weight in the brush handle as it feels like it's going to fall out of my hands quite a bit. It's not slippery, just weightless... feels cheap, especially when compared to the original sonicare Diamondclean. If you are like me, you want something beautiful in your bathroom and this brush just is not as beautiful as my white and silver original sonicare diamondclean. Speaking of white and silver, what are these horrible colors this 9900 comes in??? I have the champagne color thinking it would be tolerable but I'm definitely having buyers remorse. I have gone back to using my non smart diamond clean. One last thing, the app does not guide you to brush the biting surfaces of teeth so when you run your brush over those surfaces you will take time away from other surfaces and your app will say you did not brush for 2 minutes. The touch up option on app is hit or miss as it sometimes pops up and sometimes it doesn't. Do yourself a favor and just buy the non smart original diamondclean.
My previous experience from electric toothbrush was 10 years ago, it was just a shaking stick with small brush, so I been sticking to manual since… Decided to try again with this model and Im never going back!The first few times was pretty weird and had to learn how to not use it as a manual brush, but starting to get the hang of it a week in. Can definitely feel a difference in teeth and gum! The price is high but hopefully my dentistbill will be reduced…The only negative thing about this is the bad app and that youre not allowed to brush how you want; you can choose startpoint but nothing after that, so not getting the full benefits. Please fix!
The Sonicare 9900 Prestige delivers one of the best brushing experiences I've ever had. The brush is powerful, but adjustable for those with sensitive teeth. It holds charge very well, and the included travel case is very useful for maintaining that charfe on the go. After using this brush twice daily for over a month, I have had noticeabley whiter and cleaner teeth compared to my previous brush. The tracking options in the app, built in pacer, and pressure sensor have also helped me improve my brushing habits. The only downside I've had is cost of the unit. It is a big asking price for your average joe, but I think the product feels sturdy enough to last and justify the price.
After 2 uses, I could feel the difference in my teeth. I've used Sonicare for years, and this is best by far. No impressed with the APP, but the new head design gets between the teeth and makes my teeth feel smooth and clean. This time, I actually read and followed the brushing instructions. Hold the brush at 45 degree angle. I really don't care about the sensors, and the strength of the ultrasonic vibration seems similar to my old diamond clean. The travel case is compact. My last brush failed in less than 2 years, hopefully this will last longer. Photos show app feedback and comparison to older brush design.
I’ve used the older models and always had great success. Been using Sonicare now almost 20 years and this is the first time I got a cavity. Only thing different was that I got this toothbrush model. I had a checkup in December 2022 and was free of cavities. Then I got this toothbrush right after since my old one died and within 2 months a cavity. very upset about it. I also notice it doesn’t clean tartar off well in crevices. I have to brush for 4-6 minutes to get it super clean. I will not buy this model again in the future. I’ll stick to the midrange reliable models. App isn’t very good either.
20 days after purchase the handle battery is dead and cannot be charged. Replacement service is awful and absolute waste of time. During my 20 days experience with this extremely expensive toothbrush my observations are as follows:- Battery lasts for a few days and must be charged.- The tracking on the app is not precise and would be in error most of the time and would show that you covered parts that you actually did not cover and the opposite. This happens even if you go with the set direction and starting position. If you do not start from that point, it would be even worse. It is not reliable.- The stats in the app - extremely limited. Tips - well if you think that 3 tips that repeat all the time is usable to you, than yeah it provides you tips.- ... More20 days after purchase the handle battery is dead and cannot be charged.

The inside of the box was with dust.Absolute waste of money. The app is of very little use, the tracking is malfunctioning all the time, stats extremely limited, battery does not last for long, quality is not reliable.I would not advise to buy this toothbrush.
