WhatNameNowBGAccount Resizing of the pictures by BG won't let you see the more rounded islands type vs. the straight lines type. The pictures are just too small now. Too bad you cannot zoom in. I will keep this in mind for future reviews.

Well.... There are 2 types of bags which contain 2 basic types of prints (not divided by bag type). Then there is one damaged at the edge and tracks at the edge. About 3-4 have a few enlarged holes. Two seem to have some unfinished holes. Basically 3 out of the 10 are good while the rest is sub standard to those 3. Yes, it is mostly value for money but damaged and not even the same series in one package

WhatNameNowBGAccount Update: one broke down (it sounds like an isolation breakdown) after using it for a longer with all bursts less than 5 seconds. It was warm. So duty cycle is much less than expected. You should probably use it for very short bursts of 1-2 sec max. and then keep it off at least 10-15 times longer than that.

1000KV = 1000000 volts which should jump almost 30cm through air (found 3.4MV/m on internet) At 1-2cm it sparks. At 3-4 a thin blue line was visible (or result of previous ionization). Suggests 30-120KV. Any further seems not to spark (didn't wait too long as not to damage the device. The power usage is weird. With a 1A power supply i managed to control spark frequency with current limiting knob.
