Great toothbrush terrible battery

I purchased a toothbrush two months ago and while I can’t say that it has cleaned my teeth thoroughly as well as prevented tartar around my gums. I only SJgave it three stars because the brush heads are too big for my mouth, causing me to gag as well as the battery life. If the toothbrush is not in an upright position, it never goes to sleep if it’s laying down or if you continuously open up your drawer, it will still be on.

Great toothbrush!

Love this toothbrush! Its like the dentists in relation to vibration and function , although I am not saying its a substitute for a good cleaning! It lights up to make sure you are using the correct amount of pressure , stays charged for 10-14 days and even shows a smiley face, Sad face Or frown on the handle as To whether you are brushing long enough! I would definitely recommend this and Walmart had the best deal! Its not the newest version but I didnt feel I needed the extra gizmos

reply from Oral-B

We always hope consumers will be happy with their purchase, and are sorry to learn your iO 7 is no longer holding a charge. The Lithium-Ion battery should be fully charged in three hours, and that charge can keep your brush ready to go for up to 10 days with regular brushing (2 minutes, twice a day). Individual habits and behaviors may affect that time, but it should still be working. We’re glad you let us know you’re having this concern, so we can further assist you with this. Please have your handle with you, and call us for more help. We’re available Mondays-Fridays, from 9 AM to 6 PM, EST, at 1 (800) 566-7252.

We're surprised and very sorry to hear this. As you have heard from working with our warranty service, our brushes go through extensive quality testing, so this isn't an experience we would expect you to have, especially twice.

Love it!

[This review was collected as part of a promotion.] I absolutely love this toothbrush. I’ve used manual toothbrushes for nearly all of my life. When these style toothbrushes first came out I tried them and wasn’t overly impressed so I went back to my manual. This one has me thinking differently. After brushing, my teeth feel like they have just been cleaned by the dentist. The toothbrush settings are straightforward and easy to use. The five different settings do vary and seem to do what they are designed to do. I appreciate the 2 minute timer and the 30 second interval notices. I feel it allows an evenly distributed cleaning. I find that I pay more attention to my brushing habits with this as well. The charging base is convenient and sleek. The travel case is nice as well, though over prolonged use, I wonder how the case will hold up as it seems to be made of a lighter plastic material. Overall I would definitely recommend this toothbrush!

Great toothbrush!

[This review was collected as part of a promotion.] I have been using this toothbrush for about 2 weeks now and absolutely love it! I love the different settings it has and the smart design that tells you if your pressing too hard. Since my husband and I share this toothbrush base it's nice that he can have sensitive settings where I can have the extra clean setting on. The only downside which might be user error is that it won't pair with my phone in the app. It shows up on my phone's wifi but won't detect in the app. Overall great product!

Planned Obsolecence

Had this foisted on me at the dentist. It won’t take the regular heads, so now i have to buy the expensive new replacement brushes. They must have taken a cue from Apple. Change up interconnecting parts for no good reason so you can’t use what you already have.

Black Mold

As a dental student, I was excited to try this cutting edge and sleek toothbrush that seemed to “have it all”. I’m always looking for products to recommend to my patients to make their oral hygiene more effective and enjoyable. However, after using this toothbrush for only about 2 or 3 months, I was absolutely disgusted. I was consistent about rinsing the toothbrush off thoroughly after every use and keeping it clean, but that wasn’t enough to keep away black mold from growing inside the mechanical brush head. I ran the toothbrush under water and happened to notice small black specks falling into the sink. I removed the brush head and the inner workings of both the head and the electric toothbrush connector (cannot even be removed) we’re caked in black mold. Unlike other electric toothbrushes, this one circulates water and toothpaste through the brush head (that goes into your mouth) and the connecting pieces that get dirty very quickly. This is resulting in black mold specks actually entering your mouth directly which is a huge health risk and frankly disgusting. I’m severely disappointed in this product and the health hazard it poses for any customer using it, especially for the high cost. Please do not buy this brush until they resolve this obvious issue.

Not Worth It

Bought to improve my brushing, but the guided brush feature via blue tooth is terrible. It can never figure out what part of my mouth I am brushing. I contacted customer service and the only thing they could say about the issue was that my phone (Samsung Galaxy 20, purchased 5 months ago) was probably too new to be fully compatible with the toothbrush. They didn't have a fix, think there would be a fix in the near future or even think it was possibly a faulty brush, just an apparent known problem that they are not looking to improve. So if you are up-to-date with other technologies, this will not be for you as the cheaper models could do what this does since this app is awful. It does clean teeth well though, but like I said, their cheaper models will also do that. (Also, the brush seems wider than others towards the top, so I feel like I'm messier brushing with this)
