    Picked up this bad boy as a back-up in case the one I'm using starts acting funny. You can't go wrong with Philips Sonicare. Spend the money and see your dentist less often. Been using Sonicare for over 15 years. Best investment you can make for your teeth. Don't think twice just do it.

    I've used a Sonicare for many years now. Bought one for my mom and she loved it so much, I bought one for myself. The built in features are second to none......let's you know when to replace the brush, times your brushing so you don't under-brush, and the color is perfect in my bathroom! Highly recommend.

    Really great brush and stays charged for the longest! The only downside is that the vibration is so loud.

    I absolutely love this toothbrush! This is my second one so far and I could not be happier. Be mindful of the rubber membrane at the base of the head as it will easily puncture when cleaning, which will enable water into the battery chamber and render the device inoperable.

    Its a fantastic utility to have. It even warns you if you apply too much pressure. Even the dentist said that my teeth would not need cleaning as it had the plaque under control. The app tracks the time spent on the portion of your mouth and asks you to pay attention to those areas.
