    Brilliant electric toothbrush

    I bought this for my son and he usually uses the standard Oral B electric toothbrushes. This new toothbrush gives an amazing clean, is very quiet and my son loves the lights and features of the toothbrush to tell him if he is doing it correctly and for the correct amount of time. Great for the younger kids or adults with extra needs aswell.

    Fantastic Electric Toothbrush

    I usually buy the standard $30 Oral B electric toothbrushes, but decided to try this one for a change. I wish I had done so sooner. It's extremely quiet, has great features - I love how the timers work for each quadrant of you teeth, and how it indicates of you are pushing to firmly or to softly. The battery life is amazing and is one of the standout features particularly if you are travelling

    Great Product

    The Oral-B iO Series 4 Black Electric Toothbrush delivers an excellent clean and feels like a professional dentist polish at home. It’s sleek, quiet, and the pressure sensor helps protect your gums while brushing. The multiple cleaning modes are great for switching between everyday and sensitive use, and the app connection is a nice bonus for tracking habits — though not essential.

    A great upgrade

    I have used a cheaper Oral B electric toothbrush for several years before I then switched to just a plain old toothbrush after I got bored. However it felt like my teeth were just not as clean using a manual brush so I decided to venture back into electric toothbrushes but this time with an upgrade to the io series. I got mine in black and it is a beautiful, elegant brush. It feels sturdy, it cleans my teeth very well and it even has a handy app to keep track. I love the light that indicates if the pressure is too low, too high or just right while brushing. I also love how it is not too noisy. I took a star off simply because I find it slightly bulky and not always very smooth to manoeuvre into the dental crevices but it still cleans very well and my mouth feels much healthier since I started using it. Very pleased with my purchase.
