Has anyone else come across these toys, as manufactured by the Devil himself? DS has had one for 5 minutes and one of the teeny tiny bolts has pinged off when he was trying to undo it. Cue the whole family crawling around the kitchen floor with torches looking for the fcking thing. As far as I can tell, the loss of this microscopic bolt renders the whole thing useless AND THEY DON'T GIVE YOU ANY SPARE ONES.
