Pros and cons

According to our electric toothbrush expert

Thanks to the extra toothbrush, you can brush your teeth together.
With the smart pressure sensor, you know exactly when you apply the right pressure.
You can use the toothbrush for 2 weeks without charging in between with a 56-minute battery life.
The toothbrush has less brushing modes than the other Oral-B iO models.
You can't connect the toothbrush to your smartphone, so you don't get feedback on your brushing behavior.

Description

With the Oral-B iO 3 Black and Blue Duo Pack, you get a set of 2 toothbrushes. That way, you can brush your teeth together. You prevent damage to your teeth and gums. That's because the toothbrushes have a smart pressure sensor. They indicate whether you're brushing too hard, soft, or just right with red, white, or green light. There are 3 different brushing modes. You can choose from a standard brushing mode, a setting for sensitive teeth, and a setting for whiter teeth. This way, you can adjust the brushing mode to your teeth and needs. After use, you place it on the charging dock. With a full battery, you can brush your teeth for 56 minutes.

Review is 6,0 out of 10.

cleans well, brushing modes very unclear...

does what it's supposed to do: cleaning
fits comfortably in the hand
has three brushing teeth, but no indicator which brushing mode you have...

Cleans well, but the brushing modes are a big mystery. You can switch between them, but you won't feel any difference and there is no indicator on the brush to tell you which setting you are in! Very inconvenient if you want to choose 'soft'/sensitive gums or 'extra white'. You have no idea what you clicked...

Review is 8,8 out of 10.

Good and user-friendly product

The brushing indicator is super handy: if you apply the right pressure, it turns green; otherwise, it's white or red.
And a decent travel case is included.
Has only 1 charger in the package

Polishes very pleasantly, gives a very clean feeling
