Great product!December 14, 2008 Eric A. Kemsuzian(Buckeye Centre) Featured in Cycleworld. This unit replaces the 18yr old Lisle spark tester in my tool box. The old unit only failed after repeated abuse. Use it for safety as well as protecting 6v ignition/mag on your old iron.

i haven't used item yet, but all other sparkplug testers require some sort of grounding and this one should be very easy to use.
