Well, it's possibly repairable. I don't know much about these things.
I stopped Bridget using it when I saw bright orange flashes coming through the plastic. When he pressed the Stop button, nothing happened (cue low budget horror movie moment) and and after unplugging at the wall, it started to seep smoke so we took it out to the back alley. The power lead coming in is quite badly damaged and I suspect this was the cause.
