    Works as stated. The blue spark is very tiny but the luminescent bulb lights up spectacularly. You can present it like a nice trick to the kids. I have added a thermo-silicone paste between the transistors and their heat sinks. And finally I put a small fan from an old video-card - no worry to burn out the transistors even at 25 V.

    Nice little machine. A disadvantage for me as non-Chinese customer are the all Chinese instructions. To compensate for that, I wrote my own assembly instructions (in English). I tried to upload them but there is an error message about exceptions. If you want the .pdf to publish on the Banggood site, tell me.

    Very pretty. Note: Please pay attention to the direction of the second file and keep it from the first L1 file. Because the circuit will not work hard and correctly if the L2 file direction is incorrect.

    Delivery a bit long but all the components are there. No food provided but for the price it's normal. Instructions in Chinese but very clear electrical diagram.

    the cost of including instructions in English would be well worth it otherwise its a cool little kit. circuit board is a bit fragile as mine has a broken connection somewhere. I'm not going to waste my time looking for it over a 7 dollar kit.

    Wonderful Tesla Coil. Works as illustrated. Easy to build. Be sure to note the polarity of the 1uf capacitor and the leds. The leds must have flat sides facing the secondary coil. I wasn’t sure which way primary coil should be wired, so I wired it clockwise looking from the top, which worked. I only included two turns on the primary coil with the hope of a bigger flare. At 18 volts, I had a small flare and at 24 volts a larger flare. The FET transistors get very hot so don’t run for too long. I am looking for a small fan.

    The kit is easy to assemble. The Tesla module worked right away. The resonance frequency is 3.76 MHz (amateur radio band). The spark at the top of the coil is very small (like a dot). In daylight you have to look well, that you see something. Current consumption approx. 600mA at 20 Volt. Must be careful that the power supply tolerates the high frequency. Instruction provided is in Chinese and unusable. The placement plan with layout is faded in the instruction. Else beautiful toys. Heat sinks get quite hot.

    Cool item but need English directions LOL Takes some fiddling around to get good ark the speaker part cool but not loud enough.... Take note of how my secondary wire is in place as this had the best result I found

    this was fun to put together and arrived relatively quickly. the instructions are in Chinese, but it's simple to put together if you've got basic circuit/component knowledge.
