[This review was collected as part of a promotion.] This is a great toothbrush. I really enjoy brushing my teeth. After I brush I feel like I have been to the dentist. My mouth really feels refreshed. It is also gentle on my tongue, the roof of my mouth and my gums. I brush all of that.

[This review was collected as part of a promotion.] I'm a heavy coffee drinker, so my teeth are not so nice. I get toothaches quite often. I can noticeably tell a difference with this toothbrush. It reaches in between my teeth better than any I've used! And all the plaque is gone. My teeth look so much healthier!

[This review was collected as part of a promotion.] The Oral B series 7 black onyx toothbrush is so powerful. It has some of amazing features. The latest technology makes it easy to keep track of how long you are actually spending brushing your teeth. There are multiple language settings that make it easy to set to your likings. After using the oral B series 7 electric toothbrush I will never use a regular toothbrush again.

[This review was collected as part of a promotion.] This item came to me about two weeks ago and it has changed my life. There are three different settings and its almost like having a spa in your mouth, the toothbrush changes colors as well. Also it has blue tooth to it which I admit I didn't expect but its pretty awesome .

[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.] When I received this electric toothbrush it was one of the best toothbrush that I have ever used I have used other toothbrushes before and they cannot perform like this one has done I will definitely keep this in my bathroom for prior years I will not go back to another toothbrush ever

[This review was collected as part of a promotion.] I received this recently and it works great!This electric brush is not very loud at all compared to my sonicare one.I love the looks of it,Not cheaply made and it really does whiten my teeth.I'm so happy I got this as I have recess above a tooth from brushing too hard so my dentist told me to get a brush that tells me if I'm brushing too hard. I love the red/green light on the toothbrush that tells me if I'm brushing too hard.Makes my whole mouth feel clean and refreshed.

[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.

I purchased 2 of the IO9 toothbrushes from my dental office within the past month. The staff was ranting and raving about how wonderful these toothbrushes are and how many features they have. I was super excited until I realized that the toothbrushes that were purchased from the dentist's office lacked several features that I was told about by the staff. This is very upsetting especially because of the price. The toothbrush works well however lacks several of the features.

[This review was collected as part of a promotion.] This is a great toothbrush! I love the different settings for different types of cleaning. I've been using the whitening setting along with some whitening toothpaste, and I've really noticed a difference. I also like the timer function to stay on track.
