Unbelievably good iO toothbrush!
I tried this at CES a few months ago. It is amazing and I couldn't wait to get it for myself. I always considered myself as a good brusher-but with this iO brush, it's surprising how much cleaner my mouth feels. It's super smooth, and a lot less high pitched 'mosquito buzzing' of my old brush. T...

Does not work correctly.
I bought the battery toothbrush looking to gain an excellent brush for oral health. I bought the battery one to see if it was a fit for me before I bought the electric one. It came with batteries which did not work. No problem, I had batteries at home. The brush worked for one week. It then wi...

My teeth feel cleaner đź’«
Reviewed at
OralB.comJust restocked my Oral-B iO Ultimate Clean brush heads and honestly… game-changer every single time. ✨ The bristles are super soft but somehow deep clean like I just left the dentist. And I love that the color fades when it's time to replace it, no more guessing. If you have the iO toothbrush, these refills make the biggest difference. My teeth feel smoother, cleaner, and way fresher. 🦷✨
Best brush
Reviewed at
oralb.ca/en-caBest brush yet by far, however I wish I could mark where I have missing teeth as I play hockey and I am losing tons of teeth all of the time leaving my bare gums visible and it hurts while brushing, otherwise after the first brush my teeth were immediately white and plaque was pretty much gone and I have had a plaque problem for a long time and finally I have found the golden brush.
No USB-C Travel charging case
Reviewed at
oralb.ca/en-caThe toothbrush works well. A bit better than the 1000 series but not a big difference. More ergonomic and better looking. But in 2025, why does the charging travel case need a proprietary charger (and very polluting) and not just a simple USB-C input (like pretty much all the devices we carry when travelling)?. Very bad design.

Love my new baby

OralB.comThis is the best invention of toothbrush technology. This toothbrush literally does different colors when the right amount of brushing is done & it has an app where you can see where you have brush and where you havent. I love this. The battery lasts a lot! The price is worth it.
Terrible battery but good brushing
Reviewed at
oralb.co.uk/en-gbThis is a review from a someone who has had this toothbrush for years, tried and tested. Firstly, I do love it and don't want to part with it. There's no contest between this and a manual one…. But the reason for only 3 stars is that the battery dies mid brush, it cuts out 4 times roughly during the 2 minutes and I can't tell you how annoying it is. I do want to buy again a newer model, I would recommend to people as the pressure sensor for example Is a really good learning tool. But yeah, not something that's going to last and I have really looked after it, keeping to dry ect
Too Many Options!
Reviewed at
OralB.comYou have way too many options - I cannot tell one from the other as I need to purchase replacement heads. I did not save the box, which apparently one must do in order to know exactly what model one has.
Oral B Electric Toothbrush
Reviewed at
supersavvyme.co.uk/I've been using the Oral-B iO Series 2 for several weeks now, and it's easily one of the best electric toothbrushes I've tried. It strikes a great balance between smart features and affordability, making it ideal for everyday users who want a premium clean without the premium price tag. If you're looking for a reliable, dentist-recommended electric toothbrush that offers excellent value and performance, the Oral-B iO Series 2 is a standout choice. It's perfect for users who want smart brushing guidance without overpaying for features they might not use. Highly recommended for both beginners and seasoned electric brush users.

Great toothbrush

supersavvyme.co.uk/This is a great toothbrush, it gives my teeth a gentle clean leaving my teeth nice and healthy. The battery life is amazing which means I don't have to charge it constantly which I had to with my previous one.
