[This review was collected as part of a promotion.] This product makes you feel like you just left a dentist office. My teeth have never felt this clean from an ordinary tooth brush. I highly recommend this to anyone looking for the ultimate cleaning experience, definitely worth the investment!

[This review was collected as part of a promotion.] I've been using my electric toothbrush for about a week now and I'm loving it so far. I have really sensitive teeth so this really helps to get in and get my teeth clean. It takes me about 4 minutes to go around my whole mouth with it and I feel like ive accomplished something afterwards because of how white they look! I love the pressure guides and timing guides as well!

My wife and I both upgraded to the iO 9 series from standard Oral B electric brushes and we can not believe the incredible difference these new brushes make. Our teeth feel cleaner than they ever have before. It’s like daily having the smooth clean feeling after leaving the dentist every six months for a cleaning. Simply amazing. I think my wife was more impressed with the difference since she wasn’t as excited about paying the higher price and she is much more frugal than I am. But the price is totally worth it to her now. I would highly recommend this tooth brush to everyone. The app feature is a cool idea and I have set that up on my iPhone but I have yet to utilize the various programs and routines it offers. The brush by itself has so many features for various cleaning levels and the light indicator tells you if you are pressing too hard or too soft. Very nice feature.

[This review was collected as part of a promotion.] Oh! My! Goodness! I'm in love with this toothbrush. I wasn't expecting much but was pleasantly surprised when I started using it. I tried the intense clean and at the end it felt like when I leave the dentist after a cleaning. Pretty powerful little brush. Would definitely recommend and know that you won't be disappointed.

I am a true Oral B user. So I decided to go electric. I was super excited. It worked wonderful until today. Attached my brush and it wouldn't spin. Trashed the brush and opened a new one. Brush still doesn't spin. I'm too upset. Spent too much money on this product and it hasn't made a year yet!

I have had the toothbrush for over a year. Before the warranty ran out, I sent the toothbrush in for service. My complaint…it’s messy. Constantly dripping water. They replaced my the toothbrush handle. Nothing changed. Constantly dripping. For the money, I would not buy again. If it were free I wouldn’t take it. Less expensive model works so much better.

[This review was collected as part of a promotion.] This was my first time getting an electric tooth brush. It has a timer so you know your brushing your teeth for 2 min. It has multiple different modes for a regular brush or whitening even! It gives you a happy or sad face if you went the full time. And it’s blue tooth compatible!

[This review was collected as part of a promotion.] This product is simply amazing. I have never seen another toothbrush like it. I highly recommend this to anyone who can afford to purchase it. It has so many great features that promote tooth and gum health.

[This review was collected as part of a promotion.] This toothbrush is amazing! My teeth feel so clean after brushing. It has a lot of different setting to use when brushing. I also love the fact that it counts your time as you brush. My new favorite toothbrush!

I tried this at CES a few months ago. It is amazing and I couldn't wait to get it for myself. I always considered myself as a good brusher-but with this iO brush, it's surprising how much cleaner my mouth feels. It's super smooth, and a lot less high pitched 'mosquito buzzing' of my old brush. The ability to real time track how I'm brushing-that's a cool gamification. Brushing my teeth is less of a chore. One thing I didn't know at the beginning was that you should go tooth to tooth, and let the brush do the work-that's my helpful tip to future buyers!! I highly recommend iO!
