I have researched many days, this is the best toothbrush in the world (as of March 2015)

I have researched for a long time and can assure you that it is absolutely unnecessary more than 42 EUR for optimal toothbrush issue (March 2015)! Read all reviews on Sonicare toothbrushes and on the independent side [...]
The model Philips Sonicare HX6510 / 22 EasyClean for 42 EUR offers the best cleaning performance. All special modes in the more expensive models (Whitening, ect.) Brush exactly the same (!), Only that the brush does not turn off after 2 minutes, but for example, reserved 30 extra seconds for the longer brushing the front teeth. The same effect can get free if you turn on the EasyClean simply longer. :-)

I did not believe that brushing with more than 100% price difference identical brush and have tested it live at Saturn. Surprise: The Whitening mode in DiamondClean feels much more intense than the normal cleaning mode !!! How come? Philips has an "Easy-Start" mode integrated into the brush, so that the first 14 days are attenuated in the regular cleaning mode. In the other modes, the slowdown can not be accepted - just as it comes to the distorted perception when comparing the business.

The only comments: The Sensitive mode is actually different namely weakened permanently. Because it makes more sense to buy the sensitive brush head and brush with the normal mode.
The Diamond Clean cleaning heads are indeed better, but also fit this model - just buy it.

PS: Just do not fall on reviews in, you recommend that the ultrasonic toothbrush Emmi-Dent. Read my review to!
