They really were fantastic to have in a moment of frustration or rage - there's nothing like ending a conversation by throwing your phone at the wall/floor and watching it smash in to a dozen pieces, all of which you can later collect, easily put back together, and switch it back on for it all to be perfectly fine.
Was great in those days of teenage drama, though I would honestly love to have something as robust nowadays, some calls really do deserve that kind of treatment lol
