This is only the alarm, I installed batteries and tested it out. Works perfectly. This goes with the spy set however I believe it is the same item as other sets as well.
Out of dozens of Playmobil sets I’ve bought over the years, this is my favorite and my 9 year old son loves it. I mean it has a secret office hidden behind a bookshelf, how can anyone not love it?! Lots of cool secret places and fun details, like working lights on the board and motion alarm. Definitely recommend!!
Ordered this mostly for replacement parts and pleasantly surprised I could use my older on as add -ons with a few minor adjustments to the build. Veru happy
