Wow!!
truly just as all the other reviews have said!  it hums silently and sweeps your teeth sooo lightly....quite like no other toothbrush manufacturer out there....i'm really enjoying it and so far no water leaking into the battery compartment as i leave it horizontal on the bathroom sink (love that it comes with a cute brush holder!)...  truly amazing for the price!  can't beat it.
