And if this was the best?

When testing this brush Philips Sonicare, things were for me heard: Braun the market leader had imposed its technology, and Philips could only make up the numbers by offering a necessarily less effective alternative.

Also the Philips speech touting its sonic technology left me skeptical: "a single action fluid dynamics created by the combination of multitudes of vibration and pulsation This creates a fine aggregate toothpaste and saliva mixed in a soft fluid. enriched with oxygen. " And I do not see how the very close and very soft brush hairs, could carry out its mission.

I immediately used the brush to full power. The result seemed good. Annoyed, I decided next time to clean the left half of my mouth with the Sonicare, and the other half with the Oral-B Trizone. I have not managed to tie. I continued the test for a week, to see if in the end the supposed shortcomings of the Sonicare would eventually reveal.

Well, I still have not managed to make a difference. This Sonicare which costs 50 euros is expensive as well as my Oral-B. And it offers the most useful features: short beep every 30 seconds, stop after 2 minutes when the 4 districts of the mouth were brushed.

The relative failure of this brush, pointed to by other reviewers, is the perception of its operation in the mouth, it is not a mechanical friction, but a kind of vibration, disconcerting when you do not used to. Recognizing this, Philips has equipped the brush of a function "EasyStart": for the first 14 brushings, the brush gradually gaining in intensity until reaching 31,000 movements per minute.

It is relative failure: I remember it took me an acclimatization time before my Oral-B support. To reassure the potential buyer, Philips says on the package "Use the brush for 30 days and we will refund in full if you are not completely satisfied See conditions [...].". The problem is that they are well hidden. For this reason alone I allocates only 4 stars and not 5.
