[This review was collected as part of a promotion.] I'm a huge plan of electric tooth brushes to begin with. I've been using this tooth brush for a few weeks and I already notice a huge difference in the cleanliness of my teeth. my hygienist actually also mentioned how much less plaque I even have!

[This review was collected as part of a promotion.] I was excited to receive this product because I am always looking for a good electric toothbrush. I was really impressed by this product because it cleans your teeth very well. Feels like you just came back from the dentist.

[This review was collected as part of a promotion.] I bought this electric toothbrush for myself. It has some cool features. It can find itself on the app of you loose it. It has a circle rechargeable base. It has a digital timer. It has several types of brushing settings . my teeth feel like I just got them professional cleaned. I recommend it everyone and it's a great value for the features.

[This review was collected as part of a promotion.] The iO7 Series Black Onyx toothbrush is great toothbrush for today. It takes all the guess work out of brushing teeth. It tells you how long to brush. If you are brushing to heavy ir to light. It even tells you to brush your tounge. After a brushing with this device, you whold mouth feels refreshed.

Why would anyone possibly need or want their toothbrush to light up while charging? Not a small light that indicates charging but a glow that lights up the whole room. There doesn't seem to be a wat to stop it. Toothbrush is fine for mornings but don't use it before bed unless you want to wait until the charging is done to get to sleep.

I bought the iO Series 9 a few days ago…and I love it. However, there is no brush head holder and the brush will NOT stand up on it’s own…so not very sanitary if you like to take the brush head off after each use like I do to avoid any mold or mildew between the 2 parts.

I am a retired dentist who has used the Braun-Oral B electric toothbrushes since they were first sold, probably close to 50 years ago. They have been the electric toothbrushes on the market and I always recommended them to friends and family. The new IO series is superior to the old style, which hadn’t substantially changed since the introduction.

[This review was collected as part of a promotion.] I’ve used this toothbrush for about a week and I can already see a difference. It’s so nice to be able to select what setting to use. Feels like you have 5 toothbrushes!!! I keep it on the whitening setting and use it for 2 minutes. I love that it gives you a little smiley face when you’re done. The longer you brush - the happier the face! Too cute. Getting ready for my wedding in a couple of months and now I’ll have nice white teeth for the pictures!

[This review was collected as part of a promotion.] The iO9 Series Black Onyx tooth brush works great! It has different settings depending on what you want- daily cleaning to teeth whitening. The colored ring lets you know when you’re teeth are clean and you can move on to the next area.

I have been using on oral B toothbrush for years and my brush stopped working. Purchased a new Oral B io 9 series. Wow what difference, my teeth are cleaner, whiter and this brush definitely cleans better between your teeth. If you can love a toothbrush this is it. Totally recommend the oral B io 9 series.
