Best Upgrade

Oral-B iO Series 3

The best value entry into Oral-B's premium iO line. The magnetic motor feels noticeably more powerful than older Oral-B models, and the user-replaceable lithium-ion battery is a long-term durability win.

$70-$90

  • Compatible with all iO replacement heads
Cons

  • No app connectivity at this tier
Why we recommend it

If you want a meaningful upgrade from the Pro 1000 without spending $150+, the iO3 is the sweet spot. Reddit consistently calls it the best value in the entire iO lineup.

I have the IO3 and it feels a big upgrade to my previous Oral B. The motor is a lot faster (new magnetic motor) and feels really powerful.
