You may also select your brushing mode and scroll by means of settings and, when you begin brushing, the display screen will show a timer. Though I initially felt the display screen was an over-the-top add-on, the timer is now’s considered one of my favorite options. If I’m utilizing one other brush, I’ll instinctively look down for it.
I’ve discovered that it encourages me to brush for longer as nicely, as if I zone out or really feel as if I’ve been brushing eternally, seeing that I’ve solely acquired 30 seconds left spurs me on to finish it.
There’s a second timer within the type of brush vibrations, which provide you with a warning each 30 seconds to maneuver on to the subsequent part of your mouth, and an extended alert while you hit the two-minute dentist-recommended brushing time.

Purchase within the US and the charging puck has a regular two-pin plug. Purchase within the UK and also you’ll get a shaver socket plug. That is true of all Oral-B brushes and it’s my fundamental bugbear with the model. For brushes at this value level, we’d like to see USB charging.
The iO8, like the opposite pricier iO fashions (from iO6 and up), has three-hour quick charging through the magnetic puck. This can be a nice characteristic when in comparison with the usual 12-hour Oral-B cost, though in case you’re used to quick cellphone charging, it’ll nonetheless look like a very long time.
One slight problem right here is that it’s very straightforward to knock the comb off the puck whereas charging, so make certain it’s in a steady, out-of-the-way spot.
Efficiency
- Wonderful brushing efficiency
- Six brushing modes
- 2-week max battery life
The large distinction between iO and conventional Oral-B brushes is that conventional Oral-B brushes oscillate solely, whereas iO brushes oscillate and sonically vibrate.
The distinction is big. The iO brushing efficiency is second to none – and I don’t know anybody who’s tried it who thinks in any other case.
The iO8 has six brushing modes: day by day clear, delicate, whiten, gum care, intense and tremendous delicate. It’s one lower than the iO9 and yet another than the iO7 – precisely as you’d anticipate. I didn’t discover the variations between the modes as pronounced as another brushes however I feel there’s sufficient selection to discover a mode that’s best for you.
The iO brushing efficiency is second to none
The iO8’s battery will final for a most of two weeks. In observe, I discovered it by no means lasted fairly that lengthy however its clear battery show and quick charging did mitigate that for me.
Sharing
- Not designed for sharing
- App options shall be restricted
- Brush heads characteristic symbols to distinguish them
The iO8 can be utilized as a shared brush, though it gained’t hold monitor of your particular person brushing document on the app. Oral-B confirmed through a Tweet that though two customers with separate telephones could be capable of use all of the app’s options individually due to the Bluetooth connection (ie so long as the person’s cellphone is inside vary and the opposite’s will not be), that’s not the best way the iO was designed.
If a couple of individual is utilizing the identical brush, it additionally signifies that the comb head substitute reminder within the app gained’t work correctly.
Nevertheless, in case you’re keen to forgo among the sensible options, the iO8 can nonetheless be used as a shared brush. It’s straightforward to alter the brushing mode on the deal with in case you desire totally different modes, and iO heads are marked with small symbols to distinguish them.

Related options and app
- Actual-time brushing suggestions
- Brush head substitute reminders
- Gamification options
The iO8 connects through Bluetooth to the free Oral-B app, accessible for Apple and Android. In our check, I discovered it straightforward to make use of and fast to attach. The primary cause to make use of the app is for the interactive brushing suggestions. Watch your cellphone display screen when you brush and it’ll monitor the protection as you go.

The iO’s real-time brushing suggestions is about nearly as good because it will get. In my expertise it typically labored nicely, besides I discovered that, so as to get an ideal end result, I used to be brushing for longer than the advisable two minutes. This impacts battery life and who know – it might be inflicting me to over brush.
One of many causes you’d pay extra for the iO9 and iO10 is their 3D floor AI brushing monitoring however I don’t assume it’s that significantly better than the real-time assist the iO8 supplies. None of them give excellent suggestions however in case you want some construction to get your brushing again on monitor, they might assist.

Aside from that, the app means that you can regulate brush settings, set brushing targets, go on “dental care journeys” (maybe to enhance your gum well being), see previous brushing efficiency, gather badges and get reminders to interchange your brush head.
As a lot as manufacturers try to promote us on linked options, most don’t but add sufficient to maintain the typical person coming again. Until you actually need a strict regime of brushing assist, my guess is that you simply’ll abandon the vast majority of the sensible options fairly shortly.
Worth and availability
The Oral-B iO8’s value level varies relying on the place you’re based mostly.
Within the US, it’s broadly accessible direct from Oral-B, and from different retailers like Goal and Finest Purchase for round $249.99.
Within the UK, the iO8 had a launch value of £450, which we thought was wildly overpriced. Nevertheless, throughout common gross sales intervals, it will drop to its present value.
On the time of writing, it’s broadly accessible for £170, from websites together with Boots, Oral-B and Currys. We don’t assume you need to pay greater than this. It’s nonetheless not a cut price value however it is a luxurious merchandise that’s filled with state-of-the-art options and we expect it’s value it.
