I purchased the Black Onyx IO Series 9 toothbrush a week ago and the features are very nice, however, the traveling case is absolutely terrible. First off, it is all plastic and very cheaply made. The button does not work and I have to use force to open the case. While using force, the toothbrush and brush fall out. I talked to customer service and she was not familiar with this case and offered no support other than to, "be careful." I am very confused as to how this is not a functional issue. The reason I purchased the 9 vs. 8 was for this case. I travel a great bit and my old Oral B toothbrush couldn't hold a charge longer than 48 hours. If you do not need a traveling case, then I suggest going with a cheaper model (IO 8 or 7). The toothbrush itself is made out of plastic and slips through your hand. I love the design, but Oral B is increasing its prices and using cheap materials. My old Oral B toothbrush has some weight to it and a grip, that case was amazing. On a side note, the Black Onyx does show toothpaste. It will drip down as you brush your teeth. The larger brush head makes it difficult to hold your mouth closed to avoid this. I have a habit of removing the brush head and rinsing everything, drying, then setting aside. I do not mind doing this, but it is something to take into consideration.

[This review was collected as part of a promotion.] This toothbrush does everything but hold itself for you. It cleans, whitens, stimulates your gums, makes sure you brush for long enough...I am seriously impressed! It's bluetooth. too! You can choose the color of the light display, the language, etc. It gives you feedback on how you did. I really feel the difference in my teeth after using this. I am very pleased!

[This review was collected as part of a promotion.] This toothbrush is amazing! I love the adjustable settings, the brush end is the perfect shape, and it is the most beautiful toothbrush I've ever seen! The charger stand is discreet and fits just about anywhere, and I love that it comes with a carrying case for storage. Best toothbrush I've ever had.

[This review was collected as part of a promotion.] This toothbrush is amazing. I received it about 2 weeks ago to try and it has been amazing using it. I really look forward to brushing my teeth just to use it. It’s in different languages for you to try and has a few settings to set your toothbrush depending on what you want. A few of the settings I’ve used are daily clean, whitening and sensitive. It also has a cute little face that counts for how many minutes you have washed your teeth. Definitely recommend investing in this smart toothbrush.

[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!

As a dental hygienist I just got this brush and honestly it is amazing! I had the genius x before but this has honestly made my teeth feel freshly polished leaving them so smooth like I’ve just had a hygienist appointment! The app technology and pressure sensor which turns green when correct pressure used has honestly taken the whole brushing experience to whole new level! It is a must for everyone to get their teeth & gums in tip top shape!!!

[This review was collected as part of a promotion.] This toothbrush is so amazing. It leaves my teeth feeling so clean. I'm really fascinated by all the different settings it has for teeth care. Not to mention its also blue tooth compatible and has its own app. This tooth brush is definitely a i keeper. I think I'm in love

[This review was collected as part of a promotion.] This toothbrush is great! It leaves your teeth feeling like you've just come from the dentist. It comes with 4 brush heads, charger, travel case, and the handle. It has 7 different settings to choose from before brushing. Honestly a great toothbrush, definitely recommend!

30 years working as a Licensed Periodontal Hygienist. Dental Hygienist. I have personally used electric toothbrushes since 1980. BUY this AMAZING iOS series. I promise if used correctly, this rush gives a clean like you went to the Dentaloffice fora professional job!

[This review was collected as part of a promotion.] I still don’t know why I waited so long to get an electric toothbrush. This thing is amazing. It’s a beautiful black color with replaceable heads. It can be connected to the app to help with tracking brushes. My first experience brushing was the evening I received it. All I can say is wow. My teeth never felt so clean. I picked the daily cleaning mode and went at it. It felt weird at first because I have never used an electric toothbrush so the vibration was almost too much, but I really wanted to give it a try. I am glad I did. My teeth never felt so clean other than a dentist cleaning. My second experience I began to notice some whitening to my teeth. This was the deciding factor for me. I don’t ever think I would choose a different brush or brand! Definitely a must have!
