SenseIQ Technology for your personalized experience
SenseIQ Technology helps balance your brushing style and senses your pressure, motion and coverage up to 100 times per second while you brush. If you apply too much pressure, the toothbrush will step in and automatically adjust the intensity level, helping to protect your teeth and gums.

Philips Sonicare toothbrushes clean gently yet effectively and care for your teeth and gums with 62,000 bristle movements per minute. Sonicare Fluid Action supports the bristles to clean by driving fluid deep between teeth and along the gumline.

Overall, great toothbrush. A cleaning like being at the dentist. The downside is the mess it can make in and around ones sink from the splatter. Be prepared.

Better than the dentist
I chose a 4 Star rating because everytime I use it, I feel like I just let the dentist office. The power of the bristles slung my toothpaste across the room. I love the app. The app shoes you where to brush better at. Where you brush to hard, and more. The app can even automatically order you new toothbrush heads. I recommend this toothbrush to everyone.
Pros
Lightweight, app, great product
