Nice quality. Love, Oral-B.

We needed new toothbrushes. After looking at several models, this is a very good choice for us. Has three strength settings and a timer.

We're so sorry to hear about this. We understand how frustrating this can be. Please know that there’s nothing in our toothbrush components that would cause mold before use. Mold requires organic material to grow, which isn’t present in our brushes. While it’s rare, mold can develop after use if the brush is stored in a damp area or comes into contact with certain cleaning agents or soaps that can make the plastic porous. Cleaning the brush after each use may prevent this from happening. We'd like to connect about this and help. Please call us at 800-566-7252.

Do Not Buy!

My husband bought me this for Christmas and I hate it. By the time you're done brushing your teeth the whole handle of the toothbrush is nothing but slime from the toothpaste and your hand is also covered in wet toothpaste. Would not recommend.

We're sorry that you're not enjoying the present your husband picked up for you, Micky. We always hope consumers will love their iO2, and appreciate the thorough clean it delivers. It might help to know that you only need a small dollop of toothpaste on the brush head when brushing. Then, don’t turn the brush on until it’s inside your mouth. Once it’s working, let the brush do the work, moving it from tooth to tooth, without scrubbing. If you’d like more help with this, know we’re here to help, and hope you’ll give us a call any Monday-Friday, from 9 AM to 6 PM, EST, at 1 (800) 566-7252.

my sensitive teeth love it

Makes brushing enjoyable. I have sensitive gums, and this is one of the only electric toothbrushes that doesn't make them hurt. The timer makes sure I don't overdo it, and the feeling of the cleaning after using it is amazing.

Not what I expected

I received this toothbrush yesterday and was a little disappointed. I believe the advertising is somewhat misleading, details below, and will return it soon. My two big issues are:1 - the toothbrush heads are different that the older versions and, from what I can find out, the old brushes are not interchangeable with the new model. I did not see that documented anywhere and 2 - Also, I think, the advertising implies there is a lighted timer display on the brush someplace. If there is, I cannot find it on the brush.

Thanks for leaving your review, Robert, and we're sorry you feel this way. Oral-B iO2 Starter Kits come with 1 Oral-B iO Gentle Care brush head and 1 Oral-B iO Ultimate Clean brush head. The standard iO2 toothbrush comes with 1 Oral-B iO Gentle Care brush head. All of our Oral-B iO Replacement Brush Heads (Ultimate Clean, Gentle Care, Ultimate White and Targeted Clean) are compatible with all Oral-B iO handles, including the iO2. There isn't a lighted or visual timer on the iO 2. Instead, it has a vibrating 2-minute timer, breaking the brushing session into 30-second intervals for each quadrant. Feel free to call us at (800) 566-7252 if you'd like any additional assistance.

I bought this toothbrush as a gift for my kids, and they’ve been using it for almost a year now. One of the first things my daughter noticed was the brush head is noticeably larger compared to other Oral-B rechargeable toothbrushes. This can be uncomfortable for users with smaller mouths, but overall, the toothbrush functions well. The battery life is long-lasting and it conveniently charges on the same station as our other Oral-B brushes. However, the internal design is disappointing. While the brush head is removable and can be cleaned separately, water still manages to seep into the handle and gets trapped inside. Over time, this leads to mold growth and a foul odor, which has completely turned my daughter off from using it. She finds the smell so unpleasant that she no longer wants to even touch the toothbrush. For a product at this price point, I expected much better quality and hygiene design. It's unfortunate, because the cleaning performance is solid—but this design flaw really impacts the overall experience.

Thanks for getting in touch! We’re sorry to hear about your daughter’s experiences with her iO2. We understand these concerns are frustrating, but we’re glad to share that we’re confident we can help, thanks to the hard work of both our Quality and Safety Teams. Regarding the size of the brush head, while the iO Series 2 can be safely used by people 3 years of age and higher, the dimensions of the iO brush heads were designed for permanent teeth, so we recommend iO usage as of 6+ years. If your child is young, this could explain discomfort from the size of the brush head. You also mentioned that you’re concerned about mold growth on the brush. Please know that there’s nothing in our toothbrush components that would cause mold before use. Mold requires organic material to grow, which isn’t present in our brushes. While it’s rare, mold can develop after use if the brush is stored in a damp area or comes into contact with certain cleaning agents or soaps that can make the plastic porous. To prevent this, it’s important to clean and dry your brush after each use. Be sure your child rinses the brush head under running water with the handle on. Then switch it off, remove the head, clean both parts separately, and dry them before reattaching. It might help to know we provide a choice of Oral-B Junior brushes for children, which come with playful designs, which may suit your daughter better. Please ask your daughter to stop using the brush for her safety, then call us for additional help with this purchase. Our number is 1 (800) 492-7378, and we’re available Mondays-Fridays, from 9 AM to 6 PM, EST.

Horrible Toothbrush

A few years ago My dentist recommended I should get an electric toothbrush Sonicare. I have been using it for a little over two years. My new dentist recommended to get an Oral B. So I recently purchased a io series 2. This unit is horrible, it says two minute timer. It does not shut off after two minutes not like my Sonicare. It just gives an extra vibration. vs the vibration it gives off during 30 sec quadrants. The neck of the head is way thicker than the Sonicare. And after ever use I have to pull off the head and clean it out I do not have to do that with my Sonicare. This unit was a waste of money I just hate it.

We're disappointed to hear you don't like our iO Series 2 compared to Sonicare, and we're happy to help you. The timer is to let you know the recommended time for brushing has passed. It doesn't shut off automatically in case you need a little longer brushing. Cleaning your toothbrush is ideal to keep it at the optimal performance. If you prefer a toothbrush without an active timer, we recommend considering other models within our product range that offer customization options. Our higher-tier iO models, such as the iO4 through iO10, provide the ability to control and adjust the timer settings through the Oral-B app. With these models, you can personalize your brushing experience by modifying the timer duration or turning it off, according to your preferences. We value your feedback and would appreciate you giving us a call at (800) 566-7252 for assistance with the brush and any questions you may have.

Great

[This review was collected as part of a promotion.] This Electric Toothbrush is a high-tech toothbrush that provides a deep, gentle clean. It has a smart pressure sensor to guide your brushing and an easy-to-use display for real-time feedback. The brush head works well for a thorough clean, and the battery lasts a long time. Overall, it’s a great option for anyone looking for a more advanced, effective brushing experience.

Lots of black mold. Steer clear.

My dentist insisted I get an Oral B IO because I have crowded teeth and I would get a better clean. I ditched my sonicare for this toothbrush and I regret it deeply. I just got through picking an inch thick layer of black mold from the toothbrush connector. It is so poorly designed to have that issue. I’m mortified.

We never want you to feel disappointed when using your iO2, Chandler. Our products undergo rigorous quality checks to reach you in perfect condition, allowing you to get the ultimate teeth-cleaning experience. The iO series 2 is designed with openings on the brush heads to allow water to flush through the brush head tube and let air inside. This venting ensures the brush head dries sufficiently after use and reduces moisture inside the tube. What you have described can occur if the brush is stored in a location exposed to mold and bacteria, and the plastic comes into contact with ingredients of a corrosive nature. Certain ingredients used in those types of products can make the plastic porous, allowing dirt and moisture to find places to settle. To avoid this, it's important to always rinse your brush head thoroughly after each use to prevent residue from building up and blocking the openings. Your satisfaction means everything to us, and we'd like to learn more about your experience with your iO2. When you have time, please give us a call at 1-800-566-7252, 9 am-6 pm EST, Monday-Friday.
