So far, this is way better than my old non iO brush. The bristles does not separate & hit my gum line. It’s a bit slippery holding it so I wish it had more grip. I’m also not a fan of the pricier replacement heads.

Love this electric toothbrush. Wished I’ve purchased them sooner. Easy to use and my teeth feels so clean after. Bought another 2 for my siblings.

I have always been a manual toothbrush person and had no desire to change to an electric toothbrush. I was the only person in my house that didn’t have one. I have had good luck with the brand of toothbrush I had been using. And then I had a visit with my dentist and learned a sad truth about what my manual toothbrush was doing to my gums so it was time to make a change. I did my research and landed on this toothbrush and model. I like that it has a pressure sensor with light to easily tell you if you are pressing too hard, too light, or just right. The battery lasts long before needing a charge and the unit is quieter than the ones my family uses. It also has a built in timer and buzzes to make sure you get each quadrant of your mouth. My teeth and gums are looking and feeling better than ever before.

This toothbrush is a game-changer. It feels like a professional cleaning every time I use it. The smart pressure sensor helps me brush just right — not too hard, not too soft. The vibrations are gentle yet powerful, and the sleek Icy Blue design adds a modern touch to my bathroom. I also love the real-time feedback and the fact that it's rechargeable and lasts for days. Highly recommend it for anyone looking to upgrade their oral care routine!

[Employee of bestbuy] I honestly didn’t expect to be this impressed by a toothbrush, but here we are. This thing is amazing. From the first time I used it, I could tell it was on a different level. The bristles are soft yet super effective at getting between teeth and along the gumline without causing any irritation. It feels like I just left the dentist—every single time I brush. The handle has a perfect grip, and the overall design makes it easy to reach those tricky spots in the back of my mouth. Plus, it actually made me look forward to brushing my teeth (something I never thought I’d say). My teeth feel cleaner, my breath stays fresher longer, and I’ve even noticed my gums looking healthier after just a couple of weeks. If you’re on the fence about upgrading your toothbrush—do it. This one delivers way more than expected. Total game changer!

awesome toothbrush! wanted to upgrade to the io series from my pro 1000 for years and finally took the plunge. i appreciate how quiet it is compared to my pro 1000 and how clean my teeth feel compared to my pro 1000. the handle is nice and ergonomic too and the pressure sensor telling me the right pressure instead of just too much pressure let off is a nice bonus. its like if a sonicare had a child with an oral b. i do have some minor gripes though. seems you need to connect the app to see what mode your brush is in and the rubberized buttons collect lint from towels. overall still a great brush and is a good value since its the cheapest model with a travel case.

Cleans well. The battery life is longer than competitors. Super easy to use. Comfortable to hold

This is one of the best toothbrushes I ever had. I suffer from severe gum disease and used to have very expensive trips to the dentist since I have to have my cleanings every 3 months. Every time I went to my visits I had to have extra things done and treatments since it wasn’t getting any better. I asked my dentist to recomend something, since it was becoming quite a struggle. He recommended this, and my gums have never been better. You can change the setting to exactly what you need and the light lets you know if you are doing it okey or not. After this I can never go back to a regular brush, now every 3 months when I have to do my cleanings I pay a regular fee for a regular cleaning since my teeth and gums are so much better, it is not painfull anymore. This has really affected my life in such a possitve way, I will recommend this for anyone it is totally worth it.

Very easy to use and lightweight charges fast and clean teeth

I switched to the Oral-B IO 4 and it does a good job of cleaning the teeth and massaging the gums. The battery lasts for about a week if you use it twice a day for the recommended 2+ minutes each time. The app they provide can track your use and how hard you're pressing.

[Employee of bestbuy] Nice toothbrush. Easy to use. Nice to have different color options for each user.

BEST TOOTHBRUSH EVER!! The app is amazing with the timer and the sensor so you dont brush so hard. Only downside doesnt have the tooth coverage for it being a old model overall amazing toothbrush for the price

I decided to switch to an electric toothbrush almost a year ago and I have really been enjoying this one! There’s an app you download to see your battery life, time your brushing sessions, complete challenges and more. It has just the right amount of technology without going overboard. Refill heads can be found on Amazon for cheap. Charging is easy and takes about maybe a few hours to go from 20% to 100%. I highly recommend this toothbrush.

My son loves the way it's makes his teeth feel when he's brushing

The toothbrush works well. It cleans my teeth thoroughly and beautifully. I would give it a five but it's noisy when being used. The noise startles my pet every time I use it.

The Oral-B electric toothbrush is effective, easy to use, and helps improve oral hygiene with its powerful cleaning action.

Good electric toothbrush that doesn't cost a crazy amount. I like the led light pressure sensor and the buzzing timer aspect. I don't like keeping the charger plugged in as I have limited space around my sink, so I wish the battery lasted a bit longer, but other than that, can't complain.

I historically used a sonicare toothbrush, which was good, but wow this Oral B leaves my teeth feeling so much cleaner.

I purchased this Oral B because I was so satisfied with my last one that I must have had it for close to ten years. Changing the heads when indicated gave it its longevity. The design of the new model's brush head makes it uncomfortably large and means I have to open my mouth to reach my back teeth. That makes brushing a messy experience. This toothbrush is not ideal if you have a small mouth. Oral-B, PLEASE bring back the old design!

It was an choice. My teeth feels much cleanear. It comes with a case.
