I havent finished the first act (I bought the first 2 with some diodes and capacitors), but I can say it´s really fun. I work as a mechatronics technician so I skipped the first riddles, but they are really nice to show how if/or option work in a circuit. I will try if our new apprentices want to try it out, but even knowing most stuff it´s not like an electrical circuit in my opinion. But there is the thing you can see everything not like an electrical circuit which means it show you how stuff works. I can build an inverter and it shows how it works with physics so you get to understand and to see the functions of the specific parts in a circuit. I will probably buy the last pack later and some more plates to move stuff easier, but if you want to understand circuits I would recommend it to you. It reminds me of an experiment box about circuits which i had as a kid. And even if you dont play with it anymore and you have enough space you can leave it out as decoration for an conversation starter.
