Sealed inside, these parts are protected from water and moisture. This means that the brush is water resistant and can be rinsed under a tap and used in a shower. It is a little harsher/aggressive feeling than a Sonicare or Colgate brush. Whilst this is not exactly the best way of rating a clean of the teeth, it really feels like it has done something.
