Assembly designed to slow and is intended more for older children or even adults.
As others have descriptions in front of me, the joints are often very stiff, so that the movement is restricted or bounce the attachments when moving out of the holder.
What does not work with us, the engagement of the glass rim at one end. As well as the largest force will not help. Thus, the entire base (not the bottom plate) is not properly aligned or not holding properly.
Unfortunately, we do not work the electrics. Could be a contact fault / loose connection.
You have to operate 'elements' which are probably represent a kind of batteries, Hook. With us then but still no electricity. For this we must press on hand this component in the holder and keep it there. (For our friends - as mentioned - there was not this problem)
I hope I can fix it yourself.
Everything apart and back in business's would be annoying.
Everything else worked very well, as expected by Playmo.
