I own three of these. I found if I use a 5+5 coil of #18 Enameled magnet wire for the primary it works best with a Panasonic metallized polypropylene film capacitor of 6.85 mfd across the two outer output terminals, my flyback transformer creates 57 milliamp flaming arcs! I am going to try it with a 10mfd metallized polypropylene film cap soon. I discovered the additional capacitor trick while driving an ignition coil attached to an old flyback core with the unit, I left the cap from the ignition coil experiments hooked up when I connected my flyback, and surprisingly results where phenomenal (I assumed that the cap would slow down the frequency of the ZVS driver too much to properly drive the flyback, but instead I found it would draw 9.5 amps off of a 12 volt 7.5 amp. hr. sealed led acid battery, and produce 57 milliamp arcs of about 20,000 volts off the same battery.Read full review

Works great, high power and uses the standard dual cap ZVS design with proper components, proper power traces and a nice heatsink it would be nice to have the polarity labeled in + and - instead of chinese characters, also the R G B automatic power LED is obnoxious and i replaced it also something of note, you can drive this over 30v (i drove mine at 60v) if you remove the 12v voltage regulator and power the fan externally as long as you keep an eye on the power resistors
