I was actually a bit surprised when these were banned in the first place. They had an age range, warned to not swallow, and there are thousands of other toys out there that are as dangerous if swallowed. Well, maybe not as dangerous but still pretty dangerous if not following rules<p>The most dangerous thing i experienced with them was my kid sticking them to my PC when one single ball got sucked right through a vent and fried the mobo. Not even sure how that happened because there was so much metal between where it went and where it was being stuck to
