Pros

  • Lonasting battery (up to two weeks per charge) means less frequent recharging.
  • Comes with two brush heads, a travel case, and an extra head, making it convenient for travel and replacement.
  • Features a pressure sensor that warns if you brush too hard, helping to protect gums.
  • Effectively removes plaque and leaves teeth feeling very clean, with noticeable results within days.
  • Offers modes like Sensitive, Gum Care, and Prlean, allowing some customization.
  • SmartRing provides visual guidance on timing and pressure, encouraging good brushing habits.
  • Easy to rinse the brush heads and includes a stand, promoting better hygiene.
  • The lonasting charge is great for busy routines or frequent travel.
  • Performs more thoroughly than traditional sonic toothbrushes, thanks to oscillations, rotations, and pulsations.
  • Useful indicator light for pressure alerts helps prevent overushing.

Cons

  • The build quality feels cheap; the plastic body is slippery and cheap feeling, which can cause slips during use.
  • The vibration strength is weak, offering little effective cleaning power.
  • The larger, hard brush head can be uncomfortable and less gentle on gums.
  • Lacks clarity on modes, with no indicator for which mode is active—modes feel similar in intensity.
  • The overall brushing mechanism feels inconsistent and cheap compared to highend models.
  • Creates an odd "straike" sensation during brushing due to airflow through the head, disrupting the seal.
  • The design and feel are often criticized as being louality and unergonomic.
  • Does not include Bluetooth or app integration despite some product descriptions suggesting so.
  • Some users find the vibration too weak, disappointing those expecting a more powerful clean.
  • The product is sometimes described as the worst electric toothbrush by frustrated users.

Bottom Line

This Oral-B iO Series 3 offers impressive plaque removal and long battery life, making it a decent choice for those prioritizing effective cleaning and convenience. However, its build quality, weak vibration, and lack of clear mode indicators can detract from the overall experience. If you’re seeking a more powerful or premium feel, you might want to consider higher-end models, or other brands like Phillips, which tend to offer stronger vibrations and better ergonomics. For a budget-friendly but effective option with a good battery life, this toothbrush can still serve well, but keep in mind its build and performance limitations.
