  1. Good quality and nice design 4 Star Review

    Good quality and nice design, but the plexiglass is a bit too flexible (needs to be thicker). Exact adjustment with narrow gaps is not easy because of the flexibility.

  2. Impulse Current 5 Star Review

    Before buying this spark gap my circuit would not supply enough current to light up an incandescent bulb. But after hooking this in the circuit big current came out of the Tesla Pancake Coils.
