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.

    My mouth feels fantastic after using and my dentist told me that my gums were already looking better after a few weeks of use.

    The best toothbrush on the market. The only negative thing is that when you use it the toothpaste rolls all over to the bottom. It has some smalls holes that get filled up with toothpaste. It takes longer to clean. But overall it is an upgrade from the previous versions.

    Love our new toothbrushes. The app is great and very helpful. My only issue with the app is that sometimes when i'm brushing a certain area, it's like it doesn't properly register it and highlights a different section. Other than that, no complaints here.

    Excellent toothbrush. It's a pleasure to use, and it improved my oral hygiene. It's also very beautiful, I love that it comes with both a standing charger and a charging case.

    Does what’s it’s supposed to. The mapping is a little wonky, it sometimes reads you’re in a different section of mouth than what you’re really in.

    Oral B’s IO series is known to have the best cleaning capabilities in the market. I’ve used phillips and also other brands but this one is also the most user-friendly product ive ever used.

    Cleans good, grows mold despite regular cleaning

    Unfortunately the toothbrush head and handle grow mold after some time. I regularly deep clean the toothbrush and get all the mold out, but it grows back after only a month. After every use, I rinse out the toothbrush and take it apart to let it fully dry, but this does not seem to help the mold issue. For a toothbrush this expensive, a problem like this is unacceptable in my opinion. Mold issues aside, the toothbrush does a great job at cleaning my teeth. Even if though the app is a bit gimicky, it is cool to see some insights on my brushing habits.

    I love this brush, but its my second one in less than 5 years. The battery just stops charging or as with my most recent, after a little over a year, it instantly drains from 100% charged to zero in literal seconds. Cant get one section brushed before it dies again.

    Simply put , I struggle with multiple tooth brushes , water picks , etc. I’ve even had adult braces. The app functionality of this makes brushing visual. You can actually see what you’re doing etc. just buy it
