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.

I have been using this for almost 2 years and quite enjoy it. However, the needle stick started to be shaky and moved around after 10 months. Contacted Philips, was sent a different handle, and 8 months after, same problem happened again. Was replace with a different handle. There is a high chance the same problem will happen again with my 3rd handle, especially my warranty is about to end. Contacted Philips and asked them what the solution will be if this happens again to my 3rd handle, got no reply from them. I would recommend the diamond clean over this one. The price is a bit better and you can tell it's better made. My husband has been using the diamond clean for almost 5 years and never have any problem with it. Very disappointed with the prestige toothbrush ... MoreI have been using this for almost 2 years and quite enjoy it. However, the needle stick started to be shaky and moved around after 10 months.

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.

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.
I have had two model 9900’s now back to back. After about 12 months, the first one suddenly became very loud and did not seem to be working as well. When I removed the detachable head I discovered the metal center rod that extends from the base into the brush head to power the head seemed to be “loose”, moving around too easily. Clearly something had broken or dislocated inside the handle. I returned this unit and received a new one. The new one did exactly the same thing after about four months. I love the brush, when it works. It is quiet and the charge lasts a significant amount of time. Plus for longer trips it is easy to recharge using the smart travel case. Bu the delicacy of the unit is too much to put up with.
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 recently upgraded to the Philips Sonicare DiamondClean 9900 Prestige, and oh, what a game changer! The SenseIQ technology genuinely tunes into my brushing style, tweaking its performance in real-time. I was stunned at how it reached the tricky spots, making plaque removal a breeze. And despite its powerful cleaning, it’s quite gentle on my gums. I saw less redness and puffiness in just two weeks. The stain removal feature is a winner too, my teeth look noticeably brighter. Plus, the color options are a chic touch. This toothbrush is an investment in my oral hygiene I'm thrilled about
After about 9 months of using this toothbrush, the metal pin shaft fell off from the base of the device during bruising, and it took more than a month to get a new replacement. But the second one only lasted a month when the turning of the metal shaft stated to give a loud screechy noise, and the customer service sent me another replacement this time quite quickly within a week; but but but, the third tooth brush only lasted two month, and the metal pin started to get loose and wobbly and producing loud noise like a screaming cat!!!! I just don’t want to call them again to have another replacement…even they still give me a new one!!! What a rubbish product, all the problems is to do with that metal pin Shaft, that shows there is a serious flaw with the motor of this ... MoreAfter about 9 months of using this toothbrush, the metal pin shaft fell off from the base of the device during bruising, and it took more than a month to get a new replacement.

It’s totally rubbish.. don’t waste your money but this. It’s the worst toothbrush I have ever used!!!
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.
I have been using Sonicare toothbrushes for years, so when it was time to replace my previous model, I decided to go for the best! I am so happy with this model. It cleans my teeth so much better than any toothbrush I have ever used. I love the technology. It alerts me if I apply too much pressure or move the brush too fast while brushing. I can use my smartphone to follow my brushing session to see if I have adequately cleaned each area. There are multiple modes I can use, such as “deep clean” or “whitening” and each mode is perfectly timed. The smartphone app keeps track of my brushing habits and makes suggestions for the most effective cleaning experience. The Prestige 9900 also tells me when I need to replace the brush head and even allows me to auto order using ... MoreI have been using Sonicare toothbrushes for years, so when it was time to replace my previous model, I decided to go for the best!
