Keeps teeth clean and healthy.
on June 13, 2025

[This review was collected as part of a promotion.] Oral B io series 2 electric toothbrush gives you a dentist clean with each use. 3 speed settings to clean your teeth the way you want. The charger has a regular plug, and it is small, so it doesnt take up a lot of space on your counter. The toothbrush holds a good charge for a long time. Built in 2 minute timer. The brush bristles are round, so they cover the entire tooth and gums. The size of the brush head is good for getting around the back teeth. I actually bought the series 1 for my son for Christmas last year and he loves it. He had braces at the time, and it kept them very clean. Now, without braces, his dentist says his teeth look great, no plaque! Then I got the series 2 for me and I love it. I have been using an electric toothbrush for years and I prefer it to a manual. I do feel this gives a better clean than my old brand. I have a small mouth, so the small brush head and handle are perfect for me. I definitely recommend it.

Best toothbrush
on June 14, 2025
Posted by: korbynryan22_6233
[This review was collected as part of a promotion.] This is the best toothbrush I’ve ever used. It has 3 speeds depending on how sensitive your gums are it charges quickly (I usually put it on the charger when I’m finished). It super quiet so you don’t have to worry it’ll wake anyone up.

Would not charge

[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:

• 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.

[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!

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.
