According to our electric toothbrush expert
With the Philips Sonicare DiamondClean 9000 HX9911/94, you can choose from 4 brushing modes and easily adjust the intensity. This allows you to adjust the toothbrush to your liking. To ensure that you always brush with the correct brushing mode, this toothbrush has BrushSync. You can put any Philips brush attachment on the toothbrush and it automatically selects the correct brushing mode. Additionally, BrushSync ensures that you always brush with a clean brush attachment. That is because you'll receive a notification when it's due for replacement. Do you want to improve your tooth brushing technique? Use the Sonicare app and you'll receive feedback every time you brush your teeth.

Durability
In my experience, the Sonicare breaks too quickly, the head is then broken and no longer vibrates. As you use it longer, the "vibration" becomes less powerful each month.
The 2nd one broke after 6 months The 1st (type Philips Sonicare FlexCare HX9172/10) also broke between the 1st and 2nd year.

I like this way of brushing better than the rotating brush from that other brand.
