Quite a lot of adults dived into the bad lego scene for small kids. Its actually counter-productive: soft lego and bad-fit lego makes kids not want to use it. The top quality stuff is thou accurate, and it shows. (I had some older pre-70s lego and it was definately less strong than the newer stuff)
I watched a video too that was celebrating the downfall of the counterfeiter, and it mentioned there was something on the bricks, like a film or a grease. I can't imagine that is healthy.
