All this discussion of dead passthroughs makes me miss my old one. It was the best and lasted, like, two years. What made it stupendous? Well, it had that nokia charger plug in the bottom of a 510 battery size (no battery though) with a lovely rubbery yet still clicky button, so if I did anything funky to it, instead of tearing up the wiring or hitting the button from the side, the cord just popped out, or the button just bounced. It's one of the few dead things I've kept just in case it ever comes back to life or I can fix it. I went back to the manufacture to get a new one, but they had changed the model drastically. Although I dont know if I can go back to non variable voltage anymore. I'm uncertain if this would work so well with a wider passthrough, like we have been seeing, but on a thin one it was freaking awesome beyond belief.
