    Returned due to a few major issues

    I bought the iO9 to replace a Sonicare Diamondclean. This was my first Oral-B which I used for about 3 weeks but had to return due to a few issues and ended up getting a Sonicare Diamondclean again Pros - My teeth felt very clean after brushing. I wouldn't say it was much if any better than than my Sonicare but it did do a great job. Cons - The Oral-B destroyed my gums. I thought it was just a matter of getting used to it vs. Sonicare but my gums got worse every day and not better. They became red, sensitive and even bled. I did read other reviews before buying that had similar issues but thought they were one offs since I generally don't have issues with sensitive gums. It was an issue that could not be fixed for me which is why I returned it. The other con, which I could have dealt with if not for the issues with my gums, was that this toothbrush makes a mess. I don't know if it's the design or what but the toothpaste leaks out of the head and down your hand and arm. Just be prepared to have to wipe down after each brushing and wear a bib to protect your shirt lol. If you really concentrate and make sure your mouth doesn't open you may be able to avoid getting toothpaste all over you, I had about a 25% success rate.

    Obviously this is a very pricey device but I've tried a few electric toothbrushes (including Oral-Bs below the iO series) and there's nothing like it. I recently lost mine on a trip and tried to make do without replacing it. But after three weeks I threw in the towel and purchased this again (actually I upgraded from the series 7 to the 9). So that's how much I value this.

    Oral b 9 vs 7

    Oral-B is an excellent product and I highly recommend for anyone needing gum/plaque care. But the -9 version is not worth the extra $100 over the 7. Nicer color I guess.

    I'm not sure if all the functions on this 9 is worth the money or not. If you brush your teeth twice and day you're not even thinking of using of different functions or even get your phone out to monitor your progress every time you're trying to just brush your teeth. Lower series can probably clean your teeth just as well. Other than that, I love it.

    I really Enjoy using this toothbrush. I love all the features especially the teeth mapping function which shows what areas you may have missed or need to spend more time on. I definitely focus more on cleaning my teeth and definitely spend at least two minutes or more using this toothbrush and the app.
