This is the third toothbrush of this type that I have bought. The first used on Ebay could no longer load after a weekend. Random opening the housing, inside everything was damp and corroded. Then the second on Amazon as 2nd choice. After a few days she made use at power without the brush head bubbling noises. I turned around and saw water dripping from the bewegllichen part. (Only if was turned on) After that the sound disappeared. In my opinion, the seal was broken. Well, it was a second choice, but may not yet be. So sent back and this time bought a brand-new. Meie daughter wanted this toothbrush necessarily because they'll see the music was good, it was always exciting, what song is coming next. The songs were recognized and heard in sufficient volume (motor stops while playing Musikk) So now we have the third and it is exactly the same problem. I've decided to keep it because it works so. Solte then get broken, I hope to take the warranty service. Thus it is still quite long it is again briefly made and turned on, so that the water goes out and put the other way round in the cup after brushing on the head.
