I bought this product several months ago (about a year now) and at the beginning it was great. My teeth were clean my mouth felt healthy, until the black mold started showing up. Just an FYI after every cleaning remove the brush head and rinse it with water. Even after doing this help clean the gunk out, I still have some black residue that is on the brush head and tip of the brush unit. Wouldn’t recommend as my Sonicare was much easier to clean. I’ll be selling this one and getting a Sonicare for this reason more simple features.

[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 review was collected as part of a promotion.] Most powerful toothbrush I’ve ever owned. I have to use the very sensitive setting. I like that it has so many different brush options including gum care to tongue scrub. It has a convenient case to charge up when not in use. Disappointed that it didn’t have a vent in the case and you have to separate the toothbrush to store it. I’m giving 5 stars because it’s my new favorite toothbrush and it came with 3 extra brush heads. I probably won’t use the app or Bluetooth function because I like to keep it simple.

[This review was collected as part of a promotion.] When I saw that this toothbrush was only here as a product to review I was super excited since I've been wanting to try one of these toothbrushes. So when it finally arrived I was excited as a little kid on Christmas and after opening and using the product for over a week now I'm definitely not going back to a regular toothbrush again. The features on this toothbrush surpass all other ones by a long shot! I highly recommended this toothbrush for anyone looking for a dentist cleaning experience at home.

I am a true Oral B user. So I decided to go electric. I was super excited. It worked wonderful until today. Attached my brush and it wouldn't spin. Trashed the brush and opened a new one. Brush still doesn't spin. I'm too upset. Spent too much money on this product and it hasn't made a year yet!

[This review was collected as part of a promotion.] The Oral B serious 9 Black Onyx toothbrush is an electric toothbrush. It is Bluetooth compatible. The toothbrush comes with a magnetic charger which is really cool. It is pretty heavy and a decent size toothbrush. It came with a traveling case along with 4 brush tips! Wow I definitely did not expect that! The toothbrush gives you a recommended time for how long you should brush your teeth. It changes different colors, and tells you good morning & good evening. Displays different smiley faces which is super fun. While brushing your teeth, it tells you the right/wrong way on how to brush. The brush comes with different settings such a sensitivity, whiten, gums, intense clean, ect. The toothbrush feels amazing on my teeth. My teeth feel super clean. It feels like I just walked out of the dentist office after using this. This will be my new brush everyday. I highly recommend this product to everyone!

[This review was collected as part of a promotion.] I’ve been using this toothbrush for a few weeks now....not only do my teeth feel cleaner overall, but the technology of this thing is awesome. You can connect this toothbrush to your phone via Bluetooth and keep up with your cleanings on an app. My favorite part about this toothbrush is the colors it changes to while brushing my teeth.....red-brushing to hard, green-good brushing, blue-brushing is too soft. I tend to brush my teeth to hard, so this keeps me in check. Last, it has 8 different brush modes and keeps track of the time you brush- giving you a smile if you brush for 2+ minutes. If I could give this toothbrush more stars I would. It’s the best and coolest toothbrush I’ve ever owned!

[This review was collected as part of a promotion.] I've loved how clean my teeth feel after using this electric toothbrush. I enjoy the different settings/brush features, and the fact that the toothbrush times my cleaning. I feel like I will be very satisfied with the quality for a long time, and look forward to having a clean and fresh smile! :) I'd definitely recommend this brush to others!

[This review was collected as part of a promotion.] I have been using this toothbrush for the past 3 weeks, and it has many features that I enjoy and a couple that I would want to improve. It was very easy to follow the steps required to set up the toothbrush. I like that it has 5 smart modes. I selected and use the “daily clean” mode every day, but it’s nice that I could choose the “intense” mode or “sensitive” mode if needed, as well as “whitening” or “gum care”. One of the first things I did was download the Oral-B app, and I tried multiple times to connect my brush to my phone, but I wasn’t successful, so I can’t comment on the brushing feedback provided by the app. I like that the smart pressure sensor and interactive display provide me with some feedback about my brushing (whether I’m applying too much, too little or just the right amount of pressure and a smiley face to let me know how well I brushed). I like that the display shows me my total brushing time and keeps track of the 30 second intervals for each quadrant of my mouth. I also like that the brush pulsates every 30 seconds to indicate when I should move to the next quadrant of my mouth. It’s also nice that the interactive display tells me the remaining battery charge percentage after every brushing. I find that the brush heads are a little large and bulky in my mouth, especially when I’m brushing toward the back of my mouth. I also wish the brush handle was cradled more by the charger rather than simply being placed on top of the magnetic center. It’s very easy to knock the handle off the charger. Overall, I think this is a great, modern, unique and convenient toothbrush.
