Previously had an Oral-B Sonic Complete. But that is no longer to get. In comparison, one has in this model feel you have a helicopter in the oral cavity. From the movements and concerning the sound ... But Putz performance knotless. Holder for finally 4 brush heads also very nice and well thought out. There are several heads for this model. The only complaint on my part is the hard surface of the heads, because so yes maybe come when brushing teeth to others. As it should optimally be something slightly rubberized. Then there is of me to fifth star. Initially, nearly 140, - Euro. Euro and still recently in an action with reimbursement of 50% of the purchase price - - to have the euro as real snap - now below 80, so for almost 40.
