Customers say
Customers find the toothbrush effective at cleaning, offering multiple cleaning modes, and appreciate its intuitive design and ease of use. The functionality and durability receive mixed reviews – while some say it works well with the app and is very well built, others report it stops working properly and breaks after one year. Moreover, the battery life is concerning as it goes from 100% to zero quickly, and opinions on value for money are divided between those who find it worth the price and those who consider it expensive.

Awesome Tooth Brush!!!
Bought this new zOral B ios9 electric toothbrush and it is truly the best toothbrush either of us have used. Most impressive is the wide range of settings available from extra sensitive to a more vigorous setting. There are also settings for cleaning the tongue or gums. Easy to hold and very quiet when in use. My only complaint is that this expensive toothbrush, there was no brush holder included so I had to purchase one separately. It’s hard to believe that for $250, Oral B couldn’t provide a brush holder. Still, a great toothbrush.

It’s absolutely amazing ð! What a game changer!
I actually purchased the io 9 series on Amazon almost a month ago. I’m not happy I purchased it day’s before it went on sale. It’s whatever.. Honestly I have to say this toothbrush is absolutely no joke and worth every dollar I paid. The io series is great I went with the io9 series because it comes with 4 brush heads that’s good for around a year or more depending on how you use them . Also the lcd screen Honestly not necessary but I love it.. Most important the performance. This toothbrush cleans better than my dentist has … My teeth get whiter on every use even while I’m using mouth freshener paste. I can only imagine if I try out some heavy grit whitner paste. Also I’m using it on daily clean not the highest level. It’s an amazing toothbrush. If the battery dies it has a 2 year warranty or you can just buy a better 14500 battery Oral-B built this unit to be easy to service. As far as mold building up that’s not happening with me. I use warm water to rinse out the brush head and main unit. I almost didn’t purchase this because of people talking about mold build up! Smh . Honestly rinse it off as you would any tooth brush and dry it off and also let it air out & charge in a dry area. Please do not stick sharp things like picks in the top of the brush handle. There is a rubber seal that protects water from getting into the electronics and if you poke at it black stuff will come out because the seal is made out of black rubber! I will update this review if there are any issue’s. If this is all your seeing know I’m a very happy customer and it’s working ðª! I do not like I paid much more than the current sale price is but it’s whatever…

Hi-end electric toothbrush
Here’s my look at it:This toothbrush is for lazy people who just don’t like morning routines. Powered toothbrushes clean so much better compared to manual ones! This one has so much power my gums bled at the beginning.What I like:- long handle, can reach places you wouldn’t reach with short toothbrush- timer that shows how long do you have to brush for- battery lasts (took it on a trip with no charger, 1 week daily use – no problem, can probably last even longer)- changing this battery is possible – bottom unscrews, no glue/adhesive/buy a new unit bs! – thank you, Braun engineers- relatively impact resistant. I dropped it 3 times on a hard tile floor, and it survived the fall. You shouldn’t test it, because it depends which way it falls and on what surface, but mine is fine.- has an app. This app allows you to track what teeth exactly you have brushed, but I found it excessive, while it is a ‘wow’ technology for someone who are crazily obsessed with oral hygiene, I am just brushing without it now.Which one to pick? Honestly, I’d go with io7 if you don’t care about bells and whistles, especially if the price is tasty. If it costs around $200, go with this one.What I don’t like:- I wish manufacturer let me position toothbrush vertically in the case (make a small indentation for it to stand), instead of dismantling it every time when I travel- heads for it are kinda expensive- can be expensive, not a regular dollar store purchaseTLDR; Hi-end electric toothbrush for lazy people who would want a quality teeth cleaning with some of the features that I found excessive, but otherwise built robust and does its job well.

Best Electric Toothbrush Ever!
I’ve been using an electric toothbrush for many years and I’m not talking about the drugstore cheapo versions (although I’ve tried those as well). I typically go for top of the line in almost anything I buy because I really believe you get what you pay for. With some things you can cut corners, but when it comes to my health or my teeth, that’s not the time to make the cut.The most I’ve spent on an electric toothbrush in the past was around $180 for the Sonicare Diamondclean. It lasted me for many years, so if you break down the price over years, it wasn’t all that expensive on an annual basis. Besides, we have spent that much going out to dinner at a really nice restaurant (that’s how I typically justify the price of more “costly” items)!The Sonicare recently started acting up with it’s brushing performance and the power button was getting hard to press, so I decided to replace it. I was satisfied with it’s performance over the years, but wanted to try a round brush head this time and Oral B is the leader in that category.There are so many options with Oral B so I had to do a lot of research, starting at the top, of course. I was skeptical about the hefty price tag for the IO9, so I didn’t immediately opt for the best of the best. I read many reviews and watched several videos for the IO, Genius, and Pro lines before finally deciding to just bite the bullet and go for it!The main feature I wanted with the IO9 that the others don’t have is the 3D AI tracking. I have been getting really lazy with my brushing – walking around the house doing other things and really not paying attention to how effectively or how long I was brushing each area of my mouth. Yes, my Sonicare had a quadrant timer, but it didn’t track how much time and effort was spent on all the zones. The IO9 tracks every surface of your teeth – inside, outside, chewing, left, right, front center and front bottom. It gives you a visual display on your phone as you’re brushing so you know exactly when to move to the next area. It is taking me a little longer than normal – around 3 minutes (including tongue) to effectively brush everywhere, but that’s okay, it’s what I needed. I read some reviews and watched some videos that said the brush couldn’t determine where it was in your mouth and I have not found that to be the case. My guess is that it partially learns your brushing habits to improve the tracking. I always brush in the same order, left to right, top to bottom, so it hasn’t had any issues with accurately determining where the brush is in my mouth.I also like the pressure sensor that turns red when you’re brushing too hard or your chosen color when not brushing hard enough. I didn’t realize I was brushing harder than I should until I bought this toothbrush. The tongue cleaning mode is also useful as it’s set for 30 seconds. I wasn’t brushing nearly 30 seconds before this toothbrush.In summary, this is the best toothbrush I’ve ever used. Here are the pros and cons in my opinion:Pros:- Excellent, powerful cleaning backed by ADA approval- 3D tracking of all tooth surfaces with the app for a thorough clean- Tongue cleaning mode with set time- Larger brush head covers more area- Quiet- Fast charging- Sleek and attractive appearance and small footprint- Magnetic base that charges fastCons:- Price- The brush head is a little large. I have a smaller mouth and it fits, but some might find it a little uncomfortable- My biggest gripe is that two people can’t use the app unless you either use the same cell phone or constantly pair and unpair the base with each of your phones- The travel case only holds one brush and it doesn’t use a USB charger like every other travel device

Bought it last year as a Christmas gift and the battery is now done â¦. It did not last a great deal!We all use oral b for years, this is the first time battery life is so short

I got this a few weeks ago. I couldnât get it anywhere in Australia so had to order from us with us cables. Itâs a really nice toothbrush you do feel super clean after if youâve brushed correctly. I have come from the rose gold sonic care (another expensive toothbrush) – this is great but having to have my open and app open all the time is annoying.Look great product only thing is I donât think itâs worth the nearly AUD500 I paid. But Iâd rather have clean teeth snd have good oral hygiene then visit the dentist.So itâs worth it I get. Still canât get five stars I feel something is missing still for this price canât figure it out but something.Happy brushing!

Feels quite different to previous electric brushes, very clean finish definitely worth it.

I have severe depression and brushing my teeth can be a hard thing to make myself do consistently. Got this for excitement and for the price point you have to be using it. Plaque and tartar is literally gone. I donât know of any other toothbrush that can make everyday a dentist visit. Itâs a little harsh at times but my teeth are sparkling clean. I love the tongue setting, itâs more gentle than the other settings. I tried the deep clean on my tongue and it was straight up violence so Iâm super happy about all of the settings. The lights for how much youâre pushing are super helpful. I noticed I was way too hard on my back teeth and not hard enough on my front top. The timer is a perfect feature for me

Unfortunately the display stopped working after 6 weeks. Very disappointed.Fortunately the local Singapore Braun Service Centre replaced the toothbrush under warranty.However, unfortunately it was replaced with the only available handle color of Black, and not the great pink handle color that we originally purchased.
