This product is guaranteed to fail. There is a major flaw with this device that causes the attachment that goes into the brush head to weaken and bend over time until you can't get proper force on your teeth as it become increasingly weaker. I… Read more
bought a substantially cheaper supermarket model for overseas travel and it is far superior in its strength does not break and does a better job. Your paying a premium on this device for it to fail.
I already got a replacement under warranty and this has happened again. The design/model is flawed.
Follow-up · Flaw: weak thin piece of metal attachment that clicks into brushhead. It is a continuous loss of pressure and associated degree of vibration over time. How long did it last: 6-12months without notice. It is a continual degradation so hard to specify. Supermarket model: No idea. It was a general cheapy from Coles battery non-rechargeable 2xAAAs.

The best cleaning device for your teeth and gum health – Actually, my fill up sonicare diamond clean has been running for four years and no issues charge a super fast and the charge last for about a good four weeks. I don’t know what everyone’s complaining about. Maybe everyone has bad teeth and depressing it too hard and the toothbrush heads are pretty cheap. I get from Amazon or sometimes I make a bid on eBay and get it for a great price. No complaints. Show details · 1
I purchased a Philips Sonicare DiamondClean and have had 4 faulty units!!!! Each time they send me a replacement, the replacement unit becomes faulty again in under 12 months. DO NOT BUY! Customer support is terrible, and now they want me to send them the 4th replacement and wait up to 4 weeks for them to sort it out. Terrible! Time to find a better product. SAVE YOUR MONEY AND DO NOT BUY PHILIPS! Show details

Works well – I purchased my Philips Sonicare Diamondclean toothbrush from Harvey Norman after my trusty old oral B finally stopped working. It was on sale at the time, but at $279 I believe this is still quite a lot to pay for a toothbrush. The first time I used it I noticed how slim the head was because it was easy to get around in my mouth. My old oral… Read more · 1
B had a lot bulkier head. The philips brush head does not fill with water like the oral B head used to. My teeth feel and look cleaner.
The charging cup is great design and the USB charger and carry case means I can take it on holidays.
The reliability of Philips products have really let me down over the years, from my Philips 68cm TV that stopped working after just a few years to my multiple Philips 2 in 1 steam mops that stopped working just after the warranty had expired. I hope it is different this time round because I enjoy using this electric tooth brush.

18 months and same failure twice – My partner purchased this model for both of us in late 2021 and both our 1st toothbrushes failed after about 9-10 months with the device totally shutting down. I noticed before mine went that it went into a state of continuously turning itself on. They both got replaced and now 9 months later, same thing again for my replacement. If I was a… Read more
betting man, I would say my partner’s replacement will also fail as well shortly. No explanation as to why it would happen, but I do recall my partner was asked if we had dropped our device. In other words they were trying to find a way they could deny the warranty claim. I can say we have always been careful and treated our toothbrush as well as anything you pay good and lots of money for. Always been especially careful since the 1st one to keep it clean and dry but same result. Hopefully when we contact Phillips again, they offer to replace both devices with a model that has no issues as it is obvious to us there is a reoccurring issue with this model. The model has been by chance now discontinued. I wonder why??

Exemplary Cleaning – I have used an Oral B smart toothbrush for some years and found buying the matching smart brush heads almost impossible last year as they were no longer available anymore anywhere online or retail. To replace it I bought a top of the line Philip’s Sonicare toothbrush and Air Flosser and have been really impressed by the improvements in oral… Read more · 1
cleanliness and ease of use. I brush my teeth just prior to showering while in the shower and the brush is fully water resistant for that purpose. The toothbrush gives clear audible and vibration feedback if I use too much pressure and very easy to follow signals to move on to the next section of teeth. The matching App provides really detailed information including any missed teeth and incorrect pressure along with a complete log of my brushing. The brushes also log their use individually and the handle and app both warn when a brush head is worn out. The number of days brushing remaining calculated before replacement on the App seems to match the appearance of the bristles wear. This is very helpful in reminding me to order replacements, easily done through the App which offers a choice of retailers. Amazon deliver the replacement brush heads next day where I live with no freight charge. This is by far the best toothbrush I have ever experienced, the supplied charging cup is very convenient and the overall brushing experience and cleaning results are very satisfying. I had a minor glitch with the handle after around 1 year and it took less than a day to get it replaced under warranty. I would very happily buy the same toothbrush again.
I love this toothbrush, but design flaw + poor Philips customer service does not match price tag – 5 years of (almost) toothy bliss. Glass charger stopped working within 12 months but travel charger case is great. Apparently they all eventually get the loud noise/toothbrush head falling off issue because of a small screw that vibrates loose over time. Philips won't fix if its out of warranty and their customer service just stopped replying to… Read more · 1
my emails after I supplied serial number and a video clip of the issue. Has been 3 weeks now without response, despite me continuing to email each week seeking an update. But thankfully, you can buy a brand new replacement handle from eBay for about $100.
I have been using the Oral B 9000 in the interim, which is great, has a better timer and pressure sensor but a different feel - doesn't leave your teeth with that 'polished' smooth feeling. For me, I like that the DiamondClean is quieter (especially at nighttime so you don't wake people up) and was better for the gum line area/alleviating discomfort when I change my Invisalign aligners. I think if you like the Sonicare it's hard to go back to an oscillating toothbrush. But it is nice to have both options. The Oral B definitely seems to be better value for money and more reliable, however the battery life is nowhere near as good.
My dental hygienist hasn't noticed any difference between the two and says that brushing 2 mins bottom and 2 mins top (4 mins total) plus flossing and Tooth Mousse are the keys to helping your teeth live their best life.
I just wish I had saved myself the $$ in the first place and bought a non-retail boxed DiamondClean because a two year warranty for a $300 toothbrush is kind of a joke, especially when there is a known design flaw that eventually arises in all of them (according to Shaver Shop!) and there's no way of getting a repair outside that time period. :(

The only brand I would use – I have used the Philips Sonicare toothbrush for many years now. Got the latest one end of August 2020, after my older more basic model finally gave way after many years. The battery must have finally died, as unfortunately the internal battery can't be replaced without replacing the whole set. That is my only gripe. Considering how expensive… Read more · 1
this toothbrush is, it would be great if the battery could be changed or serviced.
Despite this, the battery does last for many years. I share my toothbrush (with different heads of course) with my family, so, it does get it's use out of it. Using a manual toothbrush is really a thing of the past, and it isn't until you use one of these, and realise how clean your teeth feels. I wish I also could splurge out on the AirFloss. But at least I can have the best of toothbrushes.
Amazing Customer Service – My Toothbrush stopped working after less than 2 years of operation. I was disappointed because while it was working I loved it. My disappointment turned around with the amazing Customer Service I received from Ruth over the phone 1-300-363-391. She was courteous, knowledgeable and I genuinely felt she's there to assist with my query. After lodging… Read more · 1
my problem, she assured me Philips will replace the handle, and I received it shortly after. Sometimes things brake and stop working, however the way I see it, the Philips Team managed to turn my experience around and I'm grateful for it. Such service makes the difference. Thank you.
Best Electric Toothbrush Ever! – My fiance came home one day with 2 of these (one each) saying we need to use these because the sonic brushing was better for our teeth. At the time I thought he had lost the plot because of the price and thought he was going crazy!.... but I have to admit, he was right! The way it brushes us like no other electric toothbrush I’ve had. It has… Read more · 1
several cleaning options to choose from (Clean, White, Polish, Gum Care & Sensitive) The standard clean will take you through all of them and switch off after 2 minutes. It sits comfortably in the hand and the charge life is much longer than others, which is really handy when travelling. It also comes with a glass that doubles as the charging cradle which is really handy and a brush cover for extra hygiene.
I’m happy to say that I love how quiet it is & the sonic vibration, and would not be able to go back to a regular electric toothbrush.
Sadly, since the purchase, my fiance passed away unexpectedly and using it now brings back the fondest of memories of when he purchased them. Admittedly, they do cost more but it’s worth every penny. Highly recommend it though!

My sonicare broke after 2 years and 2 months – My sonicare broke down after 2 years and 2 months just outside of warranty. I have contacted consumer care and they won't provide a replacement. I have told them I have financial problems and have been in hospital with covid and can't afford a new one. They offered 10 percent off but I cannot afford one after spending 300 dollars on this toothbrush. Please Philips can you send me a new handle. Show details

However, Just after my 6th one gave away around 2years mark, I finally realised it is just too much for what it is. It is just very… Read more
disappointing as one of the top brand toothbrushes. It won't charge and it would randomly turn on in the middle of night. And this time after I contacted the customer support they just simply cant do anything for me and offer me some discount for the next purchase. I think I'd like to keep my toothbrush if its still working rather than keep on having to spend $400 every second or 3rd year to replace it. Safe to say, I don't think I will ever buy another one of these and I will not recommend it to anyone else anymore.

Great for a year then it breaks – I’ve had two of these now and both after a year have broken. They are super hard to keep clean under the brush attachment so you need to ensure you do this otherwise it gets all gross. Both after a year have had malfunctions in the on off button meaning they don’t turn off and will randomly turn on. Really annoying when you’ve bought 3 of these… Read more
and all 3 have been thrown out, at $299 a pop I won’t be using Phillips again. (2 were mine, one was another family member)

DO NOT BUY if you plan on using it more than 2 years – Purchased a Sonicare HX9370 due to over brushing as I believed it was the top of the range electronic brush...only for it to not work after just over a year.

For $269, you would… Read more
expect this device to have some quality control. Do not recommend at all, all the reviews here confirm this device is NOT designed to last. Disappointing to say the least.
Love it! But I’m onto my 4th one. All dead a few weeks after 2 yr mark, except for the first one – I love this toothbrush. My partner and I are long time users. But, the toothbrush never last past the two year mark. They all die around then. It’s really pricey to be replacing such a toothbrush every two years!! The earlier version of this toothbrush seems to be of a better quality. My first ever toothbrush of this model lasted way longer than subsequent ones. Show details

Stopped working after less than 2 years – Compared with my.previous Braun OralB I thought the Philips Sonicare was about 80% as effective in terms of cleaning. Good battery life though, until it died after 20 months, started turning itself on and off in the middle of the night then died completely Show details

Broken just over two years – Considering the price and the life of the toothbrush, I would suggest anyone who is considering buying this product buy an extended warranty. It is highly likely the brush would be broken just over two years life. Having spoken to their livechat, I was told their toothbrush has been designed to last more than 5 years in a range of conditions. The… Read more
battery included in this product has been tested to perform for at least 10 years.
That's really inconsistent with the real lifespan of their product.

Poor quality and not worth the price that you pay! – IMPORTANT - Don't just read the positive reviews! Read the negative ones too!! Having now read the negative reviews, there appears to be a common issue whereby the brush just stops working. I had mine for just over 2 years and if your lucky yours will die just inside the warranty period and they may actually do something for you, however unlucky… Read more
for me the brush died just outside of warranty.
After contacting Philips via social media and then receiving an email from their customer service rep, I was advised that since I was outside of warranty and being bound by their policy, the only thing they can offer is an 'ambassador discount'.
Why would I want to spend more money on a product that is unlikely to last more than 2 years?
For what they market as a premium toothbrush and for the money you pay, one would reasonably expect this product to last a lot longer than it has, and had I known this I would have gone with a competitors toothbrush and paid much less!
I'll be raising this issue further with the ACCC, and encourage you to do the same if your experiencing the same issue.
Philips - please dont give me your stock standard response about contacting you, as I already have and its clearly evident that through your responses and your policies that you dont care about your customers.

numerous people reporting the same issue on this page. All they offered for you to purchase another one at a discounted price. Guess they have to make their money somehow. I have reported this issue to ACCC and encourage you to do the same if you're facing the same issues. It's absolutely unacceptable for a $300 toothbrush to last only 2 years.
So save your money and invest in a different branded toothbrush. For me, I'll be staying away from Philips altogether!

Brush is good when it work but worst customer service – Battery cannot be replaced which is a major disappointment but worked really well when it did. Customer service thinks by offering discount on new product they can treat like you are there to buy! They can’t resend a order confirmation once again because they sent it once! When I said their customer service is bad as they can’t resend an email,… Read more
they conveniently hid it under the Spiel of service they provide with online chat. Well all I asked for is a resend of order confirmation email which they claimed to have sent. In short the product is fabulous even though I spent $370 on it and lasted for 4 years. The customer service is disappointing Phillips if you are reading this: My partners oral b cost $25 from Coles and works well for the 5th year.

Love this toothbrush – I've been using it for 12months and I think everything is perfect about it. I've never felt my teeth that clean. I really like that you can switch between the different cleaning options. The charge lasts for month if not longer (I use it twice a day). Show reply
Excellent clean just not as durable as your old oral B – These clean your teeth much better than previous electric toothbrushes. They're not cheap but worth it. I had an issue with mine, and it was replaced under warranty with no fuss. Just don't expect it to be as sturdy as an oral B Show details · 1

I am absolutely convinced! – Introduction Approximately a decade ago, I previously purchased an electric tooth brush; and at the time, it didn't come with anything fancy, such as a charger, rechargeable batteries, a glass cup with seamless wireless charging, an enclosure with a built-in battery to charge your tooth brush on the go; and additional relevant accessories for all… Read more · 2
of your oral hygienic needs.
It was expensive and it was basic; and it didn't really do the job. Hence at some point, I ditched it and went back to normal tooth brushes.
Fast forwarding to 2019 however, I came across this electric toothbrush at a Costco store, never have I ever seen any electric toothbrush quite like this one. The price was ridiculously expensive, so at first glance and a quick look, I discounted it and moved on to something else.
It was probably after several more visits later to Costco that I then realised that the pricing became more and more affordable; and with my defacto partner in tow, she suggested that I purchase it for my needs. I didn't listen to her and instead went to YouTube and other reviewing websites to make a more informed decision.
After several reviews, I decided to give it ago and at the same time stop my whining partner.
Packaging Very well packaged and screams high-quality at every angle
Features and capabilities Yes, it does what it does and more, it will certainly satisfy most general needs without a doubt. The battery life claim of up to 3 weeks, yes, it lasts a while; there's even an indicator near the base of the toothbrush to tell you when to charge it.
Final Thoughts I like it, I really really like it. Well done Philips!
One other thought, is when you use it. Put some tooth paste onto it, water it if required and put it into your mouth before turning it on - if you don't, turning it on before, the vibration causes the paste to go every where depending on the chosen setting
Pros - placing and resting the tooth brush in the glass over the charger, really charges - really well put together and high quality construction - well packaged and accessorised
Cons - the tooth brush heads are expensive to replace - can get messy if not properly used - price obviously (its the luxury Bentley or Aston Martin of tooth brushes) - may be difficult to use based on the number of different settings the toothbrush has (its an individual tailored experience)
How did I not know about this sooner! – I'm super busy and my teeth get a little avoided at times. Now I know my teeth ARE getting the best clean in minutes. So I can continue my busy day and not worry. Best toothbrush I've encountered! Show details · 1
