Three years of ownership

Handle: $100
Heads (11 × $7.22): $79.42
Three-year total: ~$179

12 heads over 36 months at Oral-B's stated 3-month interval, less 1 head in the box. Head price: Oral-B iO Ultimate Clean 9-count, $64.99 on oralb.com. How this is worked out

What the extra money buys: Same iO magnetic drive (Oral-B's name for it; no speed published) and a pressure sensor as the Oral-B iO Series 3; the extra $40 buys 1 more mode, app tracking and a travel case. See the Oral-B iO Series 3.

Features

Oral-B app tracking over Bluetooth
Hard travel case in the box
Four modes including Super Sensitive
Lighting timer and refill-change alert
Three-state iO pressure sensor

What it does well

Cheapest iO on oralb.com with both app tracking and a hard travel case
Super Sensitive mode, the gentlest setting Oral-B offers on iO
Refill-change alert takes the guesswork out of the three-month head swap
Same $7.22 iO refills as the $330 iO9, so the running cost doesn't climb with the handle

What it gives up

No screen; mode and timer feedback come from lights only
Like every iO except the iO2, it has no published battery life
The case doesn't charge; among iO handles only the $330 iO9's does
At $100 it costs well over the iO3 for the case, app and one extra mode
