    • Works great.

This little tool is great help in telling whether you have spark. I use it for my jet skis to help diagnose starting issues. Be cautious where you hold it though! You can get zapped if you're touching the metal!

Worked as advertised, but when I first got it, I thought it wasn’t working straight out of the box because you literally have to get inches away to see the light.
