About this product
Transform your routine with the Philips Sonicare DiamondClean Smart Electric Toothbrush. This app-connected device pairs with the A3 Premium All-in-One brush head for a personalised clean. Sonic technology drives up to 62,000 bristle movements per minute, removing up to 20x more plaque than a manual brush. Multi-angle bristles reach deep between teeth and along the gumline. Choose from four modes, daily clean, deep clean, sensitive, whitening, and three speed settings. The visual pressure sensor alerts you when brushing too hard, and the rechargeable battery lasts up to 56 minutes.
The A3 Premium All-in-One brush head uses Sonicare Fluid Action to drive cleaning fluid between teeth and along the gumline for a thorough clean in hard-to-reach areas. Four cleaning modes let you switch between everyday care and targeted treatments based on your teeth needs. The travel case protects everything on the go, while the recharge indicator shows when to power up. Includes two brush heads, the A3 Premium All-in-One and G3 Premium Gum Care, plus a charging base and travel case. Compatible with the Sonicare app for a personalised brushing experience.

Great toothbrush
I picked this Phillips Sonicare a few weeks ago. It was to replace an Oral B which had reached the end of life. It is a brilliant toothbrush although the head is quite large it works well because you don’t need to scrub. Battery life is great and the glass charge is unique and effective. The various modes are good especially the whitening which is very effective.

Great for cleaning teeth questions over longevity.
Best electric toothbrush out there, for clean and dentist feeling clean teeth. I had a build up of tartar that the OralB could not shift, this helped break it down beautifully. Reliability is a problem this is my 3rd toothbrush in 4 years. The first one would turn on by itself and despite check if buttons etc it didn't fix it. Second brush the viabrator tip became loose inside the case (held in by one screw) and despite trying to fix it it was not the same. These are not cheap brushes and I'm hoping for 3rd time lucky.

Fabulous toothbrush
This toothbrush is excellent. It has a selection of settings and works brilliantly with the accompanying app, which guides the user where to brush and for how long. I thoroughly recommend this toothbrush. You will not be disappointed.

Great until battery dies
I love these toothbrushes and have had a few of them now but the batteries eventually die and you have to replace, plus they are not cheap!

Best yet!
Having read up on the Phillips Diamond clean smart brush I was excited to get one. Pricey, unless purchased on a deal, but by far the best I've used to date. My teeth and gums have never felt or looked so good.

Dreadful heavy charger! Not good for travel!
Might be a great toothbrush but sadly not one I will be able to take on holiday with me due to the heavy glass you have to use when charging it! Much prefer the older style charger where the toothbrush just sits on a plastic base. There doesn’t even seem to be a travel charger you can buy separately. Very disappointed (especially considering the price of the toothbrush!) and would not have purchased if I had realised charging method.

Excellent but poor battery life
This toothbrush is excellent, the slightly bigger brush head has taken a while to get used to, but the cleaning is the best I’ve ever had. The downside to this brush is that, you don’t get a different vibration when it’s the last set of brushing to the one you get to remind you to change area, so it seems to stop without warning, unless you count the reminders. The other point to mention is the battery life, it lasts for 17 brushes on whitening on 3 bars, which I feel is pretty poor for the price of this brush, which means you definitely need the charging travel case.

The brush and the app is a whole new experience
I've been using the brush with the app. I can see my teeth are much cleaner and the gum much healthier

Best one so far
Have had previous Sonicare toothbrushes and still have a couple of other marks in use, this is the best so far: Weight Solidity Power Design Attachments and travel case. Very pleased.
