Structure simple and fast. Holds securely in bed, cots, etc. Music box sounds metalisch and is noisy but you get used to it. Unfortunately our music box is broken after just 8 weeks, may therefore now buy a new one! It began with a wry tone, and now they no longer play the middle of the song 5-6 tones. Probably prongs broken because of low quality, too bad! Holder still perfectly without wiggle!
