PHILIPSSonicare DiamondClean Smart 9400 Electric Toothbrush, Sonic Toothbrush with App, Pressure Sensor, Brush Head Detection, 4 Brushing Modes and 3 Intensity Levels, White, Model HX9917/88

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…

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 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.

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.

This is the 3rd Sonicare I have purchased, of the previous two, one failed for a battery (after warranty period), the other failed after excessive vibration from the handle and very loose drive spindle (also out of warranty), surprise surprise, my current one (this purchase) also failed with the excessive vibration, fortunately under warranty, however the actual customer service from Sony has been awful. I returned the item over 2 weeks ago and still have not received my replacement even though they said it has been dispatched. The tracking information is in Polished and translated seems to be telling me they have received the item a good few days ago, not yet out for delivery....Arrgggggg!

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.

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

Nice one
