BUT: We first got an obvious returns. The packaging was already damaged and the Assembly (Mobile for gripping arm) was very loose. As a result thereof, the part made unbearable Klack- and grinding noises. Actually more of a clock and about as annoying as a dripping faucet.
Thanks to Amazon the next day we had spare and the new device (this time without utility / mounting tracks) runs quietly and orderly also hakelt not. Clearly, the mechanism can be heard, but rather as a slight humming, no comparison with the first device, which apparently had a real hit. Maybe should Grobmotoriker receive no right to return: - /
So anyone who complains to his unit over the loud sound, maybe you should try another. The hanging of the engine in gripper arm is easy, dismantling only if you have previously noticed how the parts interlock. Who simply as rear channels attracts here as a Batty, will damage the engine and the next customer would be then ...
Our small (10 weeks) is in any case fully and enthusiastically about to start to fidget and struggle on as soon as the part is in operation - at least for the fast songs at the beginning. The last three registers are then more likely to fall asleep and here it dawns then regularly away.
My Conclusion:
Really nice and pleasant sound Mobile with the advantage of being able to use it as a portable music makers later. But who gets a wrong dismantled returns, will be annoyed at the loud engine noise!
