iO3 Ultimate Clean Electric Toothbrush for Adults | 3 Smart Modes | iO Pressure Sensor | Tuft-in-Tuft Bristles | IPX7 Waterproof | 2 Year Warranty | Round Brush Head (Ice Blue)

Recommended by Harvard Medical this is the best entry level electric toothbrush for you add to your arsenal. A few important considerations you would want to keep in mind to get the most out of it: 1) HYGIENIC USAGE TO AVOID MOULD: You need to take apart & rinse the foam off the brush after every use, leave the head as well as the handle to air dry outside to avoid growth of mould from moisture that gets trapped in spots you cannot reach if the brush isn’t opened up. If you’re lazy and just throw your brush around in your bathroom, this is not for you. I’ve gotten used to this ritual after every use and just leave both parts to air dry in a glass and have never faced any issues with mould. 2) PAIR WITH A SOFT MANUAL TOOTHBRUSH FOR COMPLETE CLEANING: This does not completely replace a manual toothbrush. I still use a regular manual toothbrush followed by my IO3 and my teeth feel the best they have. One does not replace the other. The iO3 can reach spots your manual toothbrush cannot, and guides you on the perfect pressure to apply to your teeth. Another friend I recommended this to and started using it was advised by his dentist to not give up manual brushing during his checkups. I have found the best solution is to employ both methods to cover all aspects of cleaning your teeth. My teeth have felt the healthiest, cleanest and brightest since I have combined both. 3) BRUSH HEADS NEED TO BE REPLACED EVERY 3 MONTHS: They’re readily available on Amazon however this will be a recurring cost, so keep that in mind. Still cheaper than paying thousands at the dentist, so the cost is worth it. 4) DOES NOT HAVE FAST CHARGING LIKE THE IO8/9: I tend to leave it overnight for a 0 - 100 charge so it’s not a problem for me, but something to keep in mind for your daily usage. If you can go for the next model, I would recommend it for the screen as well as the fast charging.

Definitely feel better using this over traditional brushes be it cleanliness of the teeth or the gums.

Everything is good....but replacement heads are overpriced...

hopeless product..waste of money..dead in less than six months

I was using an Oral-B Pro before this, which was okay, but the iO 3 is a completely different experience. I was really impressed when I first bought it, and I’m still just as happy with its performance. The only downside is that the replacement brush heads aren’t very easy to find. And when you do find them, they may be available in a different colour, if that matters to you.

l've always hated the feeling of plaque buildup, but since using the Oral-B iO3, that's no longer an issue. The brush does such a thorough job of cleaning my teeth, and I love how I get feedback on whether l'm brushing too hard. My gums feel so much healthier, and the round brush head design seems to really reach into places my old toothbrush couldn't. It's also pretty easy to use, and the three modes give me options depending on what I need that day. If you're looking for a toothbrush that actually makes a difference.

Very good

Got rusted.. Later oral b replaced with fresh one

Die Zahnbürste hat viele verschiedene Programme genau passend zu den jeweiligen Wünschen. Durch die farbige LED ist das Zähneputzen eine reine Freude und man sieht direkt, ob zuviel oder zu wenig Druck ausgeübt wird.

Bello, comodo e funzionale

Last year I bought an Oral B Pro 4 as it had a lion battery and was towards the top of the range. A great brush, slightly better than any other Oral B I have had in the last 10 years, and a good price on Amazon in the Jan sale. I read great things about the IO range recently, and that they were all the same (ie Io3-Io9) other than connectivity, displays, faster charging etc, so I went for the basic Io 3 from Amazon Warehouse at a good price. It is like the difference between B+W and a colour tv; a push bike and an electric bike; a propellor plane and a jet; compared to the pro 4. Instead of a buzz it whines it goes so fast, the brush must rotate 30 x faster, it is near silent, but so powerful, it is an increadible clean. There is literally no comparison between the Io range and the Pro range. HIGHLY recommended, you will not need another brush, ever. The heads are a bit more than the Pro 4 heads, but I got two from Oral B (when registering the brush, which gets it a 3 year warranty) for fifteen lbs on an offer they had so that's virtually a year's worth. And you don't buy a Ferrari and put cheap tyres on it off a Fiesta! Buy the base brush the Io 3, it's the same as the Io 9 basically without the fast charging and colour display and 6 modes you will never use.

I've had this toothbrush since March 2026 and have previously had their older model Oral B toothbrush which lasted me for over 4 years. This iO model is awful, impossible to clean properly and grows mould inside the handle and on each toothbrush no matter how much I clean them both and in what. Awful design compared to the original. Would not buy again and will need to buy a new one purely due to being unable to clean this one to a good standard due to the design of it. Also thr heads I keep purchasing I need to change monthly if not more often. Money wasted.

Great tooth brush but the charger lead is quite short and there are no 'built in' aftermarket chargers for this product. The charger male part is a different shape fromthe older modles
