- •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 higher-end models.
- •Creates an odd "straw-like" sensation during brushing due to airflow through the head, disrupting the seal.
- •The design and feel are often criticized as being low-quality and unergonomic.
- •Does not include Bluetooth or app integration despite some product descriptions suggesting so.

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.
