This tester works but, in my case the cable barely worked; way too short. The connections were not snug resulting in me having to secure each end in each hand while a second person started the vehicle. The tester worked, the light was fairly bright, but the design/length needs to be improved.

Easy to put in line for trouble shooting lack of spark.

Put on a tiller to check spark. Didn't flash. Then put it on a running mower,no flash. Finely found my old tester. There was spark on both. There are reasonabley priced quality ones out there, but I believe this isn't one of them.

Wish the bulb inside was a bit brighter but works as expected. Boot is too big for smaller spark plugs.Doesn’t work well on the short plugs had to trim the boot.

Handy tool for determining spark in cases where the ignition system is in question.
