Professional Clean at Home
This toothbrush is a total game-changer! Every time I use it, it feels like I just had a professional cleaning at the dentist. It’s powerful enough to leave my teeth feeling incredibly clean, but still gentle enough that it doesn’t cause any pain or discomfort. The battery life is impressive — it lasts a long time between charges — and the travel case makes it super convenient to carry around while keeping it protected and charged. I love not having to worry about losing it or finding a place to recharge constantly. Overall, it’s easily one of the best toothbrushes I’ve ever used!

Happy customer
Best tooth brush I have ever owned it’s not just a toothbrush it’s definitely in another level I actually get a dentist clean feel everyday that I use it it’s one of those things that you didn’t know you needed it till you got it and now you can’t go without it kinda of thing yes it’s insanely expensive but for what it does I feel like over time with consistency you could potentially have less dental visits because your getting your teeth and gums throughly clean daily sometimes 2x a day will help to keep them healthy thus saving you money

Flawed and Messy Design
This is the worst electric toothbrush I have ever owned. The iO brush heads are different than the older Oral-B design. These iO brush heads have two holes at the top that allow prolific amounts of toothpaste and saliva to enter inside the stem on the brush head. But what is even more flawed is that there is a large third hole at the base that allows a lot of the toothpaste to leak out while brushing your teeth. This design makes it difficult to use without making a mess everywhere. The head design is also harder than it should be to keep clean, and quite frankly, it seems unhygienic to me. The connected app is somewhat of a gimmick to me. It always says that I am missing spots that I clearly and thoroughly brush over. I stopped using the app after a few weeks. I just switched back to my older Philips Sonicare. Not only do my teeth feel better after brushing with the Sonicare, but it was an absolute pleasure not to have messy toothpaste leaking out of the base of the brush head and making a mess everywhere while I brushed my teeth. Buying this toothbrush was a complete waste of money. I plan to stay with Philips Sonicare from now on.

Investment
Expensive toothbrush. But worth the money for long-term dental hygiene it’s like I took a drill to my mouth. It was a little overwhelming at first however, second use was very much easy. I am impressed with how well this toothbrush, my mouth feel clean improvement in my gum, health more importantly, I went on a trip and had to use a normal toothbrush and it just felt completely wrong. I highly recommend this toothbrush as an investment. , I went on a trip and had to use a normal toothbrush and it just felt completely wrong. I highly recommend this toothbrush as an investment to your dental hygiene.

Toothbrush good
My orthodontist recommended me this a while ago and now that I bought it, it has made my teeth cleaner and the gaps less full of gunk
