The catch
The proprietary iO brush heads cost nearly double what older Oral-B or competitor heads do, making this an expensive toothbrush to own, not just to buy.

Spec, translated

The 'iO Sense smart charger' uses sensors to guide your brushing across 6 zones of your mouth, aiming to solve the problem of missed spots, but it's also the feature that inflates the price into luxury territory.

Lab notes
The observations that actually change the buying decision.
01
The iO magnetic drive is a legitimate engineering upgrade over oscillating motors, offering a smoother and quieter operation with precise micro-vibrations.
02
The 'iO Sense' smart charger is the primary cost driver; it tracks brushing coverage in real-time but requires app engagement to deliver its full coaching value.
03
At nearly $380, the price is set by the color screen and a charging base with sensors, not a proportional increase in cleaning power over models costing 70% less.
04
No battery life specification is provided, a significant omission for a premium portable device. The included charging travel case implies it cannot last a typical two-week trip without a power source.

Why you should buy

This is for the user who wants the maximum amount of data and feedback on their brushing habits and is willing to pay a steep premium for that coaching. It also appeals to those who prioritize the quieter, smoother feel of the magnetic drive motor.

Why you should skip

Anyone focused on value can find comparable cleaning results in brushes under $100. Users who dislike relying on a smartphone app for full functionality will find the core 'smart' features of the iO9 a chore to use.
