Arrived in a month (good for South Africa) . Plugged it in, runs well at 3V, hits current limit of supply. probably better to run it at higher voltages for reduced heat. Device doesn't heat up too much if it doesn't run for a long period of time. don't want to stress test it any further than 30-40 seconds. Easily puts holes through cardboard. Overall, I am happy with my purchase!

All 5 step up transformers worked fine and delivered about equal energy. Don't test them on someone or an animal. That causes a nasty experience, the HVDC sparks up to 4CM gives a jolt capable of shut down someone temporaly, dependin on exposure. Use them for only a few seconds to test or for experiments, otherwise they will be damaged very fast. Not 400KV but for sure 40KVDC. Use a sparkgap limiter for prohibit overvoltage, the HV capacitors will spark internally and game over. In my opinion ideal for selfdefence (build in a plastic flashlight) and use one 18650 fresh charged. Persons with bad intentions can be stunned very easily and have after contact no idea to get the same experience again
