Oral-BiO Series 7 Electric Toothbrush with 2 Replacement Brush Heads, Black Onyx

Great quality toothbrush! My teeth look and feel much cleaner now. It can be charged about once a week, so it's easy to take it on a trip without the charger. I am very pleased this toothbrush.

I love this toothbrush! This is my third because after a few years the battery fails to charge. I called Oral B after the first one died and they sent me a new one free. I bought this one and had to send it back to Amazon because the Oral B box that held the toothbrush was so beat up. The outer box was perfect. What a disappointment when you need a new toothbrush! I could have gone to Walmart and saved $30. Really disappointing.But the toothbrush is amazing! I always get high marks at my dental cleaning.

Funny to think that years ago we wouldn't have dreamed of having a computer built right into our toothbrush. I't just some bristles on the end of a plastic handle, right?I'd say it's hard to justify the price for this toothbrush, but to be honest I can't. To me it's worth every penny. The last visit to the dentist had the hygienist telling me that my gums looked better than the previous visit; that's enough to convince me that the extra tech that has gone into the iO 7 was worth the extra I had to pay to get it.It's quieter than the old Oral B Pro that I had, and leaves my teeth feeling a LOT cleaner. The brushing action has the familiar oscillation but also incorporates micro vibrations, which help remove anything that shouldn't be on the surface of your teeth. The accompanying app. (which you download onto the phone) helps encourage good brushing habits, and maps out your teeth into 6 different 'zones' monitoring the time spent on each, as well as brushing your tongue, rinsing, flossing, etc. I used the for the first few days, but sometimes you just want to brush your teeth and get it over with, ya know? The app. also awards you with medals for different behaviours, and I can see how having a simple reward system like that can also encourage good dental hygiene.The charging stand has been redesigned, and the 'peg' from the Pro charging stand has been removed, and a strong magnet built in to hold the brush upright and in place. This is a huge improvement, and results in a much cleaner charging stand (if you've used the Pro for any length of time you'll know what I mean!).The replacement heads aren't the cheapest, but replacing one every three months is not the end of the world for a healthy smile.I consider my money well spent.

This is the best electric toothbrush that I have owned. Does a perfect job every time. Get a perfect clean in two minutes every time

I purchased this toothbrush in white for myself in December 2022, and since it performed well, I decided to buy another one in black for my partner in January 2024. However, the experience with the black model has been disappointing. While my toothbrush is still functioning properly after more than two years of use, my partner’s stopped working in March 2025, which raises concerns about the product’s consistency in quality.Given its price—not only higher than the white model but also more expensive than many other options on the market—I expected greater durability. It is unreasonable for an electric toothbrush at this cost to have a lifespan of only 14 months. In terms of performance, while it worked, it provided adequate cleaning, but its lack of reliability makes it difficult to recommend. There are more affordable alternatives with proven durability that offer a better return on investment.

I have hated electric toothbrushes all of my life. They just really annoyed me. My teeth didn't feel any cleaner than with a manual brush. I tried this one as a last resort. I'm getting older and my teeth have to be taken care of! There are different levels you can use to get the best brushing specifically for you. I use the intense level which is, as promised: INTENSE! You can really feel the difference after using this toothbrush.Its like having your dental hygienist there with you! My teeth really feel so clean and smooth after brushing with this toothbrush. I really feel like my smile is brighter and my gums are healthier too. (there is a setting for your gums too)! If you're in the market for an electric toothbrush, I strongly recommend this one. It is expensive, but to me it is worth what I paid for it. I really feel like I'm taking care of my oral health every time I use it. Aside from all of that good stuff, I got the black color which is super cool looking and I love the beautiful LED colors too. Overall, a huge improvement on anything else that's out there!
