Previously I had used the battery toothbrushes Oral Pulsar. When I now bought this unit and used for the first time, I just thought 'wow - there goes off the post! " Since properly plugged Power behind, then the gentle signal, move to the next quadrant, so that you have the security of having cleaned all four areas sufficiently. In addition, you need a lot less toothpaste (I use mostly Colgate Total). After brushing your teeth are really bare as in the dentist-dental cleaning and if you then at that puts a phase gum massage (very pleasant!) Saves it to let make the 2nd time in the dentist. I can highly recommend the Pulsonic without compromising! And who needs only ne habituation, can indeed times start with the above mentioned battery toothbrush, so costs about 5 euros. Although it does not have the strong cleaning power, but is still one of the best among their peers.
