not very happy

poor battery life, they take longer to charge, the brush heads wore out within the first week, would not recommend to a traveler. I feel cheated out of 200$

reply from Oral-B

Vern, we know how important it is to have a toothbrush you can count on, and are happy to help. Please know, we have many quality checks in place to ensure only the best products reach you. This toothbrush should take around 16 hours for a full charge, however, the amount of time the battery lasts can depend on several factors, including frequency and time spent brushing, pressure used, and even the modes being used. The brush head lasting only a week could be caused by brushing too hard -- too much pressure makes the bristles wear faster. Also rinsing a toothbrush under hot water, or soaking it in a solution, will soften the bristles and cause them to wear out more quickly. So that we can help you further, please give us a call at (800) 566-7252.

Great clean

The vibration seems to really clean my teeth. I was disappointed that this uses different brush heads though since I had a small stockpile for my previous brush.

Design flaw (mold and mildew issues)

I would seriously avoid this product. The Oral-B iO cleans my teeth really well, but there are two design flaws that drive me crazy. First, the charging base is shaped like a little bowl. Every time you put the toothbrush on it, water drips down and collects in the base instead of running off. After a while it gets gross, with slime and even mold if you don’t clean it constantly. A simple sloped design would have solved this. Second, where the brush head connects to the handle has a bunch of small crevices around the magnetic connection. Water and toothpaste get trapped there, and it eventually turns into black slimy buildup that’s difficult to clean. For something that spends its life in a wet bathroom, this seems like an obvious design problem. It’s a great toothbrush, but I expected better from a premium product. It shouldn’t require this much maintenance just to keep it clean. It should have been designed with an emphasis of proving mold and mildew development but instead it actually allows for it to grow. I looked into taking apart the base and trying to 3d print my own base but I’m just gonna find a D product that is not designed like this. I’m guessing most of which are to cut costs.

We are truly sorry you are not getting the experience you expected with the iO series 5 toothbrush. We want to assure you there is nothing in our toothbrush components that would cause mold, as mold requires organic materials. While rare, mold can develop after use if stored damp or with certain cleaning agents. We value your feedback for improvements, and if you need further help, please call us at (800) 566-7252.

Oral b IO series 5

Arrived extremely fast. Everything was in great shape when it arrived. Nothing was missing. Item was new and sealed in orgainal packaging. The instructions say let charge for 30 minutes, during that time i downloaded the app wrote the review for the company that i purchased from, by then it was 53% charged. I bluetoothed my phone and the brush. The app is insanely accurate, the brush works well beyond my expectations. The brush isnt quiet but its not as loud as many other mechanical toothbrushes I've used. I am very pleased, non the less. (My husband was sleeping and he didn't budge.) However the cleaning you get from this brush is WOW!!!!! Definitely worth every cent. The toothbrush is light making it easy to apply the perfect amout of pressure. I have rather sensitive teeth and it felt great. The viberations were not bad and my mouth feels clean. ( I was timid because of my hand held toothbrush does cause pain in a couple areas, not this io) The app was helpful in knowing when you can move forward, I like to brush for 3 mins sometimes longer, the app allows you to adjust the time to to your desired time limit. Giving me more control over the feeling of cleanliness I like to have after brushing. The app also asks if you have any bleeding from the gums, and allows you to set individual goals if you choose . Also the app allows you to set other preferred settings such as ring color and brushing setting . If I could give a higher rating I would, to both the company I purchased from, American Hub and Oral B. I am sure that if you decide to purchase this you WILL NOT REGRET IT. By far the best toothbrush I've ever used and equally amazing company.

Better than Colgate Hum and SoniCare

Both my husband and I switched the Oral-B iO, downloaded the app on each of our phones, and have been enjoying a cleaner feeling brushing experience, along with feedback than we’ve have before. We’re very happy with the switch, and in time, will move our son from a Colgate Hum to an Oral-B iO, too!

Brighter Smile

We have been using Oral-B for years on the adviice of our dentist. As an early Christmas gift to ourselves, we decided to upgrade to Oral-B iO Series 5. In less than a week our teeth look whiter . It is easy to use and has different options to use for teeth and gum health.

Professional results at home!

Fantastic toothbrush. Bought these for myself and my wife on the recommendation from our dentist. From the very first use we were impressed. Teeth feel like they have been professionally cleaned and polished after every use. The pressure needed for cleaning is clearly visible with the LED light to help those like myself who have a tendency to brush with too much force. READ the instructions as this is not your typical battery toothbrush. GameChanger in teeth care.

Had a previous version that lasted a number of years. This replacement does not disappoint.
