PHILIPSSonicare DiamondClean Smart 9400 Electric Toothbrush, Sonic Toothbrush with App, Pressure Sensor, Brush Head Detection, 4 Brushing Modes and 3 Intensity Levels, Black, Model HX9917/89

I used to use the Philips toothbrush years ago but didn’t like the way that it tickled my mouth so I then went over to a brun toothbrush. But now after 20 years, I’ve come back to the Philips toothbrush and it feels a lot nicer when you’re brushing your teeth yes I can recommend this toothbrush to anyone that’s looking.

This is a replacement for my old and discontinued sonic ORALB toothbrush. I much prefer sonic than the rotating ones so did my research and this one ticked all the boxes. It leaves your teeth really clean, not too noisy, different vibration patterns depending on the selected setting, great for travelling, haven't used the app yet. The glass charger is bigger than I expected and it took me a few days to get used ot it, overall I think it is worth the expensive price tag and I am happy with my purchase.

I didn't realise how I was brushing my teeth ineffectively until I started using the provided app.Not only does it give you a timer but it ensures that you are using the correct pressure and clean your entire mouth properly, reviewing bits that you missed. It also adds the options for a tongue clean and mouthwash rinse.It does take a while to let the brush do the cleaning and just hold the brush over the teeth without reverting to stereotypical toothbrushing hand movements. I had to retrain my brain!The battery lasts a long time and the brush lets you know when it needs a recharge.The replacement heads are quite expensive but this is because they have they Wifi sensors in them to give the feedback to the app.I found after a while I stopped using the app as I had remembered how to clean my teeth and couldn't be bothered with the extra fussing.Love this toothbrush and I personally feel and prefer the sonic cleaning from this brush over the rotary cleaning of an OralB.

Crap. The metal part where the toothbrush heads are attached got loose making the device unusable in less than a year.I used the same model for more than 10 years before this one. That died the same way but served me 10+ times longer than this one. I requested a repair - we'll see; I don't have huge expectations. Definitely won't buy a Philips toothbrush again. Most probably gonna switch to Suri.

Most would stay away from paying so much money for a toothbrush and they are right, there are so many others, very good ones too, cheaper.But, WOW, if you find a good deal for it, treat yourself and buy it. It is powerful, full of features. Your teeth will thank you.

I have used Phillips Sonicare brushes for many years. They usually last two or three years then get very noisy as whatever bearing wear out. I do not have a problem with that as they all have twice daily use and seem to clean my teeth well. No hesitation in buying this one and so far continues to work well. App for me is a bit of a gimmick but no problem as you do not have to brush with it.

I had had a similar toothbrush for a number of years & needed a replacement. It’s amazing, cleans your teeth like no other, I love it…

This replaced a Philips sonicare whose battery failed after 7 years - they last !Cleans more efficiently than my previous version, improved design over the years.The case with the inbuilt charge lead is a great idea
