It is the first time that I write a product review. The reason is that this product really me skin off your feet! With my normal toothbrush I'm not always come to all parts of the mouth, for example, I've always had problems with calculus formation directly where the tip of the tongue is there. My dentist had, however, told me once a few years ago that electric toothbrushes are mostly not good. (Topic: enamel) This recollection, it was refreshing, and I asked my dentist again. He advised me to a sonic toothbrush but I would be willing to spend some money. No sooner said than done, first I ordered two different Oral-B. Both were sent back, and ordered a Philips. As usual, the order was quickly in the house, and I grabbed the unit. Processing made a very good impression, only times Download After the toothbrush was charged I have completed the first tooth cleaning. WOOOOW, simply amazing! The cleaning performance was really impressive, just simply pull over the teeth and everything is clean. Even the hard to reach places everything was cleaned. If you have previously tested the Oral-B time and then switching to the Philips, the worlds are again! It is yet to be seen how the toothbrush will propose long-term test. One thing is clear to me, however, to a normal toothbrush, I will not go back. From me get this product an absolute buy recommendation !!!
