This clock is really great. The animal sounds are difficult to hear. The only shortcoming is the glass. In a Kinderuhr it would advantageous to use plastic. For us the glass is in fact already destroyed because our son always only must adjust to a new and therefore the clock first so had in hand before it can be hung. Unfortunately, it is then again dropped him and the glass broke. But nevertheless it is still functional. We have it all glass removed and then hung up.
