    This is my fourth sonicare since it came out. This unit works with an app to help you learn the best practices for good oral hygiene.

    This toothbrush really makes your teeth feel clean and after a few weeks look whiter. I am very happy to continue using Philip's toothbrushes.

    I had been considering an electric toothbrush for a while, read reviews online and finally determined that the Philips was the best one. I did not like the price but with using my Best Buy rewards it brought it into what I considered to be an out of pocket cost I was comfortable with. I still wasn't convinced that it would be better than just brushing myself. I then began using it after a dentist visit. I can honestly say me teeth have never felt as clean and nice after brushing. I also like the bluetooth connection and yes I use the app daily.

    The application along with the toothbrush makes a perfect combination for your teeth. The toothbrush comes in a very nice travel pouch and the charging cup always keeps your toothbrush charged. If im being nip picky i wish the ppuch came with a usb to charge the toothbrush on the go, but for my type of getaways which is 3 to 4 days this toothbrush easily makes it to through the weekend. I would highly recommend this product if the price seems reasonable to you. Investing in your health personally to me is not a waste of money.
