[This review was collected as part of a promotion.] I got this iO9 Series black Onyx electric toothbrush. At first I was like what is this and how do I use it? It doesn't have instructions saying what some things are even. But after I actually used it I loved it. I love that it has lights and you can set your base color. It flashes red when I brushed too fast and green when I brush just right. This toothbrush is awesome. It made my teeth feel clean and stayed fresh.

[This review was collected as part of a promotion.] I can’t explain how amazing my teeth feel after using my new toothbrush only just a few times now. I’m excited for my teeth and their new potential. My teeth are getting whiter and i feel them to be so much cleaner. I can’t wait in between brushes now and get excited every time I get to use it. It feels very gentle but it does such a thorough job cleaning my teeth. I love my new toothbrush!

This toothbrush has completely upgraded my brushing routine. The clean it gives is superb and it’s made me much more aware of the pressure I apply when brushing. The timer feature is also excellent so I don’t have to wonder how far along I am if I zone out while brushing.

The Bluetooth is abysmal. Half the time it doesn’t understand that I’m in a different quadrant. I could easily get over that but wanted to mention in case you’re a completionist like me and wanted your health app to keep track. Most importantly is the mold. I’ve had this brush about a month and I brush twice a day. I take the head off after each brush and since the bristles and inside the head and base. One day I noticed some blank gunk. I thought maybe it was the design. After careful inspection, I realized it was mold. I’m going back to sonicare flex. That toothbrush lasted over 7 years and I wish I hadn’t thrown it away for this moldy garbage. I’d never recommend Oral B I/O.

[This review was collected as part of a promotion.] Oh! My! Goodness! I'm in love with this toothbrush. I wasn't expecting much but was pleasantly surprised when I started using it. I tried the intense clean and at the end it felt like when I leave the dentist after a cleaning. Pretty powerful little brush. Would definitely recommend and know that you won't be disappointed.

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.

[This review was collected as part of a promotion.] I love this iOS series 7 brush. The many cleaning modes gives me the choice for choosing what fits me best. I love the sensitive modes since I have always had problems in that area. It brushes smoothly and cleans with little ease.

Purchased this a month ago and really feel it provides the best cleaning and brushing I have ever had. Only reason for a 4 rating... no stand available for the brush heads. When having my wife and I utilizing the IO Brush... no place to dry the brushes or stand them while not in use.

[This review was collected as part of a promotion.] It came in a neatly packed box . The oral b io series is the best, I could ask for. It’s so gentle on teeth , it has a very good micro vibration.The round brush, helps I professional cleaning.There is a smart sensor, that protects your gums and enamel when u brush too hard. So you can see the sensor react and brush accordingly.They have this new feature that is called 3D tracking and AI recognition it uses an interactive color display. This helps us to clean all areas of the mouth, it guides us where to clean and how much pressure is needed. There is a 2 minute timer, which warns us every 30 second.The brush comes with 7 modes like daily routine,gum care,tongue cleaning,whitening,sensitive, intense, super sensitive. You can sync it to your smart phone. So your smart phone can remind you on updates, there is a happy and sad smiley.. the sad smiley means u either skipped brushing or did not brush effectively. The happy smiley, says ur tooth is healthy. This helps in tracking your brushing habits. I got -3 replacement brush, travel case, charging unit. My tooth are really sensitive and I spend a lot on dentists and hygienist.. This has been the best, by far , I can vouch on this brush. In this 3 weeks , I can feel how good my tooth has changed. It’s stronger and healthier. It helps me clean the places that I missed. It guides me, where to brush. Definitely, would recommend to my near and dear.

[This review was collected as part of a promotion.] Oral B always makes great toothbrushes! Love the features on this. So many choices for how I want to clean my teeth. I love the power brush because I don't have to wonder if I'm scrubbing hard enough or not, the brush does it for me!
