    Great brush. It is quiet and does a good job. Hindsight, I didn't need all the bells and whistles, but it is a good brush.

    Awesome product! Had the previous model for over 12 years and the battery was starting to wear out. Definitely worth the upgrade!

    There are features you won't use, but after the right dentist visit, you'll suddenly need. I love how the handle reads the brush head and adjusts the program automatically

    I recommend this product. It cleans very well, it's light weight. My older Phillips toothbrush was heavy. I really hope whitening function works, just started using it.

    This Sonicare Toothbrush was purchased as a replacement of a much older model. The BrushSync technology is nice and I no longer have to worry about choosing the correct setting for the different brush head types.

    Sonic Care was kind enough to send a replacement, unfortunately it was also dead on arrival. First one the metal shaft became loose and the replacement wouldn’t charge. They take 7 days to send a replacement. When I called to inform them the replacement also didn’t work, they told me I need to let it charge for 24 hours. Ok cool but wouldn’t it light up and show it charging like the other exact same model does in the exact same charger? Apparently not. Moral of the story buy a replacement plan for best buy if you purchase this product. It works great, when it works

    Teeth feel like they have been professionally cleaned every time I brush. There is a sensor if I brush too hard it stops and the wireless charger rocks! Fist time electric toothbrush and I love it

    With a manual toothbrush it's easy to give a short, low quality brush and head off to bed. This makes sure I brush my teeth for 4 minutes twice daily. I literally feel the difference.

    Great toothbrush. I love the feel of the matt handle. It lights up hot pink on the bottom if you brush too hard.

    I like the tooth brush. I’m just wondering if all the different modes actually says what it does? I see or feel no different. When changing the modes
