Would not charge
on June 14, 2025
Posted by: mdeiss_1958
[This review was collected as part of a promotion.] I was excited to try this toothbrush. Upon receiving it, I tried to charge it, and it wouldn't charge. After many attempts to get the toothbrush to charge, I was unable to. I would not recommend this toothbrush based on this alone.

Works

[This review was collected as part of a promotion.] The noise level is non existent almost . It's very quiet . Price range is on point and not too expensive. Battery life is weird , unsure if it's fully charged or not or if the charge dock is defective but seems to last pretty long. Design is good and the cleaning performance is top tier .

[This review was collected as part of a promotion.] This toothbrush is very nice and works really good! I like the red light so you know if you are brushing too hard. Good battery life and it’s not loud! Easy to charge and it cleans really nice.

My #1 Clean Machine — Sleek, Smart & Surprisingly
on June 18, 2025
Posted by: Anonymous
[This review was collected as part of a promotion.] Swap your boring brush for this sleek black gem from Oral‑B—the iO2 Series is basically brushing goals unlocked.
✨ Gorgeous design
That matte-black handle is chic and minimal—no bulky gadgets here. It’s lighter than its fancier siblings (~117 g), comfy in hand, and won’t clash with your bathroom aesthetic .

🌀 Impressive clean
Powered by iO’s oscillating + micro‑vibration tech, that round brush head literally cups each tooth and blasts plaque (up to 100% more vs manual brushes) . It totally nails the dentist‑clean vibe I crave after my morning grind.

🧘♀️ Super‑gentle for sensitive gums
Three easy modes—Super‑Sensitive (the default), Gentle, and Daily—switch by holding the single power button. Gum pressure sensor kicks in to slow the motor and flash a red light if you’re brushing too hard .

🔇 Calm & quiet
Not gonna lie—it’s louder (~72 dB) than higher-end iO brushes, but still smoother and less buzzy than older Oral‑B mechanicals . Night‑time brushing? Totally doable without mom storming in.

🔋 Ridiculous battery life
This is where it stole my heart: up to 5–7 weeks on a single charge (37–53 days in real tests!). Sure, charging takes a full day, but you’ll barely need to do it .

✅ The Wins:
• Timeless black design that hides toothpaste splatter like a boss
• Deep, dentist-level clean
• Kind to gums (pressure-sensor smart!)
• Zero charging stress—seriously crazy battery life

⚠️ The Trade-offs:
• Needs cleaning beneath the brush head—some users reported gunk buildup/mold if left damp   
• No glowing pressure ring like the iO3+, just a tiny front light that’s easy to miss 
• Lacks Bluetooth/app integration (and honestly, I didn’t miss it)

✍️ Final Take:
If you’re thinking of making the switch from a manual brush or outdated electric one, the black iO2 is a smart move. It’s stylish, gentle, and gives you that polished mouth feeling every time. You just have to stay on cleaning routine (rinsing & air‑drying it after use).

P.S. It’s called “entry‑level” iO for a reason—it’s the perfect blend of sophistication, simplicity, and performance.

Reachable

[This review was collected as part of a promotion.] I received this for my honest review. This toothbrush is working great for me. It’s rechargeable and very convenient. It’s very easy to use and also includes a timer so you know you’re brushing the right amount. My teeth feel very clean and fresh after use. I would recommend this toothbrush.

Great clean feeling!
on June 24, 2025
Posted by: tarai5_9135
[This review was collected as part of a promotion.] The iO2 electric toothbrush has made me finally ditch my manual toothbrush. I like that this brush is sleek and doesn’t take up much counter space. The battery life is long and is quick to charge. I like the three speeds so you can customize your clean and that there is a red light indicating when I am using too much pressure. This toothbrush does the work for you. The best part is the just left the dentist clean. It helps my teeth stay clean and polished everyday.

Didn’t work
on June 26, 2025
Posted by: stephanieb24_7908
[This review was collected as part of a promotion.] I honestly feel it’s unfair to rate this product but Influenster keeps asking soooo…when I claimed this I was really excited bc I already have an electric toothbrush that was getting old. Once I claimed it I realized this is an older model that’s not being sold in most places anymore. No problem. But then when I went to charge the toothbrush, it didn’t work. I did all of the troubleshooting online and reached out to support but no response. I hate to give this a 1 but the toothbrush doesn’t work at all. Very disappointing.

This made me an electric toothbrush believer!
on June 26, 2025
Posted by: reviews_with_ky_9329
[This review was collected as part of a promotion.] I received an Oral-B iO2 Series Electric Toothbrush at no cost as part of a Influenster program.
Before receiving this product, I only used manual toothbrushes like the one you get at the dentist. I have several family members who use electric Oral-B products, and was excited to give this a try.
This toothbrush has a very long battery life. It can stay alive on a single charge for several weeks. It also comes with an easy-to-use charger that the toothbrush stands on. There are three settings for the intensity of the brushing movement. My teeth are fairly sensitive so I stuck to the lowest setting. The toothbrush can also sense when it is near the gum line.
After over a month and a half of use, this toothbrush has won me over! I’ve noticed notably less plaque near the gumline and the built-in timer is helpful for knowing when to switch to a different part of my mouth. I also had a dentist appointment today in which I was told I had the cleanest permanent retainer they have ever seen!
The only downside about this toothbrush is that it does not come with a carrying case. As someone who travels once every month or two months, that would be incredibly convenient (although I know newer models do come with one). Overall, I highly recommend this toothbrush and look forward to continuing using it.
