    Best one out there, even my dentist took notice of the improvements. The battery on full charge lasts a long time, like over a month! Thank

    Bought this Sonicare toothbrush after my last one stopped working after 5 years. Very impressed with the functions and features that came with this one and leaves a clean feeling when done. The ability to change cleaning styles is very nice and has a nice carrying case. Would recommend to anyone needing an electric toothbrush.

    This toothbrush is great but I am worried about the power button. After a month's use it feels like it is ready to give out. it is intermittently working and feels loose. That being said.... teeth are whiter and mouth feels cleaner.

    Took me a couple times to master using this brush with the app, but it’s very simple and very effective. My dental hygenist was impressed with how clean my teeth were at my latest checkup. I’m thankful for the different speed options. I found the highest setting (recommended for my current brush head) to be too much. The middle setting is perfect.

    This was really a spontaneous buy, but I’m not disappointed at all. Not that it necessarily cleans better than other toothbrushes, but it teaches you basically how to brush (properly). I started off using the app and now I have no need for it. The charging cup is the best thing about it as well as the case it comes with.
