The greyhound is delivered ready (with metal chain and hook on the "roof", which is not visible in the picture), you only have to remove the protective strip from the battery and it can hang directly. The battery is even charged, so you can test it right in a dark place.
The whole part acts extremely valuable and 17.99 EUR for this appear to me to be a very fair price. Our 10 year old daughter found the lamp "magical" and would now also one for your room, also standing at 3 birthdays, so I order another which.
I just hope that the interior is just as valuable and it lasts a long time - but as long as this is otherwise, it runs.
For safety's sake, I have ordered from Amazon anyway, because they are always very accommodating with complaints ..

Update: Au Weija, the lamp is not lit just one night and then - I have to return it, thank goodness that was on Amazon as anticipated no problem. We have a very well-insulated house with 2-fold glazing - the tinkling of wind chimes is indeed ansich a pleasant sound but it's also so loud that you could hear it inside clearly. My daughter liked it, but I would have if it had since worked on, on hanging off a tree. In this respect, I now do not know even how many points I should give it ..
