Packaged very good.
it very good
Well made from quality materials. Works well.
I bought two; the first failed after about 20 uses; there was a discharge noise in the area of the high voltage coil; the second is still functional; I did not find the replacement coil; I opened the defective coil that is stuck in the resin, it seems to be a 15-25kV transformer with a primary of approximately 20 turns, the secondary coil with 6 sections isolated one by other and a ferrite core of 2cm long; one of the high voltage coil terminal is connected to the secondary; I did not identify where the high voltage discharge was; I will try to replace it ... considering the number of electrodes it is a still good value for price, but i recommend the product only for hobbyist.
