Product Review

When we were children, we were always full of expectation of the world. We imagined stepping on the water, flying in the sky. I imagined that when I pick up a lamp, it will shine sitting on my hands. It doesn't need to nailed to the ceiling or pinned to the wall anymore. Now, this Tesla coil makes dream true. What a marvelous little thing! It lights the bulb without any wires. This Tesla coil is a wonderful conversation piece, and a cool piece of art even just stands on your desk.

Attention:
1. Not suitable for people with electronic medical instruments;

3. It would produce a smell as the artificial lightning would turn O2 into O3 in the air, which is totally fine for your health at this level of density;
4. Avoid placing it on a metal desk, as metal would absorb the model's energy;
5. The arc is completely fine to touch, the current is pretty low;
6. Do not touch the lighter which would cause sting to your finger;
7. It is suggested that you turn off the model by the switch on board, rather than directly pulling out the USB cable.
