    iO4 Better

    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.

    Awesome electric toothbrush

    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.

    Great toothbrush!

    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.

    Absolutely love my new Oral-B iO Series 4!

    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!

    For my mom she loves it

    [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!
