Great toothbrush, but compared to the FlexCare ...?

I clean for many years with Philips sonic toothbrushes my teeth, because I'm very satisfied with the cleaning results compared to a manual toothbrush. With the Diamond Clean I have now the third generation. Before, I used the FlexCare about 3 1/2 years, until my trick with the throw down no longer brought the full power and the brush finally gave up the ghost.
After much deliberation, I then decided to use the Clean Diamond. Why long? Well, at least I think EUR 200 for quite steep, considering the price policy of recent years pursued a rapid charge. But what, exactly? A Brief Introduction after 3 weeks:

In my view, there are the following positive aspects:
- Look smart, no question, and many times praised here
- Charger in Travel Case with integrated USB connector, class idea because I travel a lot
- New brushes design, cleans better than the FlexCare in fact and feels more enjoyable

But compared with the FlexCare I find some negative aspects:
- The angular design and the smooth surface is not so sure in his hand as the FlexCare. Especially annoying when the handpiece when changing from one side to the other is rotated in the hand.
- There is only one (1) button! I rinse my brush after use under running water. One must then either 5 times so that pressing the button again it emanates, or about 10 about waiting, put them back a simple press.
- Why is there no UV equipment to disinfect more? I use my old from the FlexCare!
- The Travel Case is quite large in natura

Conclusion:
At the expense of design functionality has been lost. Yes, she's smart, but important but also a good and safe operation is not only a good cleaning result.
The only real improvement I see in the brush head. It also goes to the FlexCare! The pure swinging back and forth "is identical for both, of the technical data forth much I no differences.
Therefore, should really think twice about any if he is willing to spend EUR 200. For the FlexCare there are attractive offers.
Therefore remains to be seen whether the Clean Diamond after 2 œ years gives up the ghost, like my two predecessors ...
