I'm just having trouble finding the right way to think on it. They are pretty impressive. Back at the turn of the previous century, very similar devices were being sold as medical cure-alls, soon to be followed by radium salts. Given the technology of the time, getting 50kV at a couple hundred kHz in something that you could walk around with was pretty impressive. Some of those devices are still out there working.
