Christmas spirit - but not for small children

I have this fairy lights ordered for the nursery because there was a decorated tree and was missing a little light on it. The fact that the chain is battery betriebend was decisive for the purchase since no power outlet is available near the tree.

The chain looks really nice, has a small or medium-sized tree, the correct length and makes a pleasant warm white light.

If I could, I would deduct half a star because after two days of a bullet was already next to the tree. I suppose that one of the children has very badly about it. The ball could be good but put off again.
For small children households therefore not suitable (also available as on the packaging) - otherwise buy recommendation!
