Philips Sonicare 3100 HX3675/15 Duo

The strong vibrations of the fibers drive microbubbles into the spaces between teeth and along the gum line, creating a feeling of refreshment. In just 2 minutes, you’ll get the same results as two months of manual brushing.** 31,000 brush strokes per minute gently cleanse teeth, remove plaque, and provide exceptional daily cleaning.
Plaque removal is 3 times better than using a manual toothbrush.
The battery lasts for 14 days, so you can go a long time without charging
