Bought brush for about 400 dollars which included spare brushes, which as you could imagine, soon needed replacement.
Ordered a set of 3 for over 40 dollars, which took over a month to arrive!
The first Sonicare DiamondClean brush we had lasted about 2-3 years before it no longer worked, and Philips neither had parts or repairs for it.
The brush itself does a good job, but it is a pity that Philips uses such unreliable technology and is so greedy charging so much for just three plastic brush head replacement.
My opinion is that the Philips Sonicare DiamondClean is not worth the money

I purchased this product HX9954/56 sometime 2018. Cleaning teeth well has never been that easy before. Lately I noticed some loud vibration noise. I decided to contact the care centre. Thanks to Ivan & Karen A, I was told that warranty is still valid, and they will sending a replacement. The whole process was quick and easy.

I purchased one of these 5 months ago and even though I've used it properly, Philip's promised oral care ended up being the opposite and apparently could have led to major issues if I'd kept using it. What's worse is that I called the customer care team and they wanted me to pay to 'go to a doctor to get scans' to send them before they would even have anyone look into it. (I knew they meant dentist but it was such a cop-out as 1. you can't 'scan' the enamel I think, and 2. it means they what me to shell out over $120 just so they will look at ...

While this is not a cheap product it's probably worth the expense. If it helps to improve my overall dental hygiene / health then it's worth the investment.
The app is helpful to encourage you to adopt good habits, though I'm not sure how accurately it tracks movement

This toothbrush is amazing! I have sensitive teeth and was afraid the brushing will be too aggressive when using any function other than Sensitive. After trying, I can say I use all functions with no issues. My teeth feel clean and polished and this feeling continues for much longer than when using my previous toothbrush.

The design of Philips Sonicare DiamondClean (Rose Gold in my case) is also beautiful and the brush handle assures a nice grip. Box contains all noted items, however, the plug is an EU one rather than a UK one, but you can e...

It is very good and keep my teeth in a healthy condition and the most important feature is I can check the cleaning status from my app. I need charge it in once a week

We had several Philips Sonicare models in the past years.
This one with no doubts is the best in terms of the actual performance of the toothbrush.
This is the main plus of all these particular set of new models.
The rest of the features like an ability to communicate with the mobile device is from mine point of view a little bit premature (however it is definitely the right way to go!). Would be nice if the algorithm behind censors could workout more precise the real place where the brush head is working (currently it is only defining up...

A bit pricey, paid a fortune to get this product, but so in love with it. so Pretty. Tried with my airfloss, I think I might not need to see a dentist for a very long time. Highly recommended

After spending so much money on manual toothbrushes, I was constantly being disappointed with the quality. Barely lasting a couple of weeks before going to the bin, I decided to invest in a good quality electric toothbrush to help save some money in the long run, but also maintain my nice smile,improve my dental hygiene and cleanliness of my mouth. I noticed a massive difference within a week of using my diamond clean smart tooth brush and the overall quality of my smile and cleanliness of my mouth has improved immensely and it’s encouraged me ...
