    Best Electric Toothbrush

    Wow! This is the best electric toothbrush I have tried. I had plenty of doubts at the beginning to purchase it but I decided it to try it. My teeth have never felt cleaner and whiter. It is just amazing all the functions that it has. It’s like having a coach to tell you how to brush your teeth properly.

    Cleans so much better than a regular toothbrush. The round head gets behind teeth and to the very back. Love the timer.

    This electric toothbrush is by far the best in the market. I have tried many battery operated toothbrushes in the past and this one definitely blows every single one of them out the water! Definitely recommend giving it a try.

    Very well thought out program. While I do not get too in to the blue tooth capability I find that the toothbrush does what it is supposed to do--clean my teeth really well. I upgraded from the Oral-b 8000 which in of itself was a highly rated brush. This one with its new brush heads is the best

    It is a very good product with only one drow back - the are no 2 min stopping. You have to have a perfect hearing to hear 3 bibs that specifies 2 min cleaning time. For older person it may be problematic.

    Made the switch to Oral-B after 15+ years faithful Sonicare user. Extremely Happy I finally took the leap! LOVE LOVE LOVE my new ORAL-B iQ. Highly recommend over the competitor's, wish I made the change sooner.

    Absolutely the best toothbrush I’ve ever owned

    This brush has expensive replacement heads, but does a great job and has a cool mobile app that helps promote good brushing habits via gamification. The sensors built-in enable you to see where you brush well and where you may have been missing good brushing. There is also a helpful light (green / red) that lets you know if you are using too much pressure — and monitors the amount of time in-use which is bad if too short or too long. All the data is kept historically in your mobile app to help you learn and improve. Overall, it is a great toothbrush!

    Not good

    Cleans well. But coming from the Premium series im very very disappointed with battery life. It lasts only one week and if i turn bluetooth off it lasts 8 days. Also that stupid screen that you cant even see while brushing your teeth turns on with the minimal movement. Transporting the toothbrush expect to lose some battery live just for the normal movement of a bag.

    Been using this for about almost 4 weeks now and I like it. I like the features it has especially the pressure level to alert if you are brushing too hard. Overall a great electric toothbrush. Though I wish it was a bit cheaper.

    Luxury looking electronic toothbrush! I love all of the features including daily clean which I use with the Bluetooth feature. It shows how long and where to brush your teeth. It even shows where and how long you’ve used too much pressure. I highly recommend this investment!!!
