Perfect. I had an oral B sonic bought in 2008 for 120 euros! Who still work perfectly after 5 years but problems finding the heads easily and above all the desire to change (I'm a geek by nature). This, bcp low Size is just perfect, do not hesitate. If vosu know Oral B is the same efficiency. The finish is good month as the sonic but who cares :) 50 euros plus 3 year warranty offered with the extension after recording, it's all good. Personally smeilleurs the brushes are the floss share purchase separately.
