Pros — What I Loved
☑ Premium Clean Without the Premium Price
The iO3 uses the same advanced cleaning tech from Oral-B’s high-end iO range — but at a much more affordable price point. You really can feel the difference after just a few uses. My teeth felt polished and looked noticeably brighter after a week.
☑ Smart Pressure Sensor
This feature is a game-changer. It helps you avoid overbrushing (a big cause of gum problems), and the real-time colour indicator (red/green) makes it super intuitive.
☑ Sleek Design + Travel Friendly
It looks great sitting on your bathroom counter, and the included travel case is sturdy and compact — ideal for weekends away or holidays.
☑ Quiet Yet Powerful
Much quieter than older Oral-B models, and still delivers that deep, thorough clean you expect from their oscillating heads.
☑ 2 Brush Heads Included
Most brushes only come with one, so the second head is a nice bonus, especially at this price point.
Cons — What Could Be Better
No Bluetooth/App Connectivity
If you’re into tracking your brushing habits via your phone, the iO3 doesn’t include smart features like the iO6–iO10. That said, not everyone wants their toothbrush linked to an app.
Limited Brushing Modes
Only three modes, which are plenty for most people — but if you’re used to more personalised routines (like “gum care” or “intense”), you’ll have to go up a model.
Replacement Heads = Pricey
The iO series uses new-generation brush heads, which tend to be more expensive than older Oral-B styles. Keep this in mind for future replacements.
Who’s It For? 👨👩👧👦
- First-time iO series users
- Anyone upgrading from a manual or basic electric brush
- Great gift idea for him or her (packaging & travel case makes it feel premium)
- Budget-conscious buyers who still want a deep clean
Final Thoughts — Is the Oral-B iO3 Worth Buying?
Absolutely. The iO3 is the perfect middle ground: premium performance, stylish design, and essential features — all without going overboard on price or complexity. It's gentle on gums, tough on plaque, and makes brushing feel more like a self-care ritual.
TrendTested Rating: ★★★★☆ (4.5/5)
“Less tech, more clean — the iO3 is a sleek, smart investment in your smile.”
