Customers are saying

Customers recognize the iO Series 9 Connected Rechargeable Electric Toothbrush for its exceptional cleaning capabilities, overall performance, and ease of use. Many appreciate the long battery life, useful app, convenient travel case, and helpful pressure sensor. However, some customers find the price to be high, and others have noted that the brush heads are different from the older Oral-B design.

    I read somewhere that using an Oral-B requires you to brush differently. I guess it’s something I couldn’t get right because I had more gum issues than ever before. I switched back to my previously used electric toothbrush (different brand) and my issues went away. Perhaps if someone has been using this brand and has the brushing techniques required for the Oral-B, this may be for you. Unfortunately the satisfaction guarantee period is too short for me to return it.

    It is an amazing toothbrush. It is very powerful and has multiple brush modes, would be five stars if it wasn't so expensive.

    The best toothbrush I have ever purchased, period. We do have the series 7 in the family, and while the series 7 is enough, this one kicks it up a notch. It has real time mapping of your mouth as you clean, two more clean settings, OLED display, and a carry on charger similar to the Apple pods. If you are a frequent traveler this comes in handy.

    This toothbrush has amazing features and cool settings to customize it the way you like! I am really satisfied with it’s performance, and not to mention, it makes almost no sound at all! The charging block and case are very ‘professional’ looking and convenient where the case charges the toothbrush as well! I’m very happy with this product and 100% recommend.

    I purchased this one for my son. His previous Oral B toothbrush finally would not hold a charge after 10 years. I purchased an iO 9 for myself in June (after my first Oral B toothbrush stopped holding a charge after 25 years). I loved my new one so much, I bought one for him. My teeth have never felt so clean!!
