Handy little diagnostic tool
👍 Pros: Works fast for testing HT supply to a spark plug. Sturdy and simple — no settings to fiddle with. Great for DIYers doing engine diagnostics. 👎 Cons: Only shows presence of spark, not strength or timing. The short lead length might mean you need to lean over the engine more than with longer cables.

Does the job
Great little time saver when troubleshooting a small engine. It answers the question as to whether or not the spark plug is getting any electric juice.

Easy to use most of the time
A good little gadget, it worked well on my old 1970 mini, but wouldn’t fit my Alfa as the plugs have an extender & it didn’t fit onto that

Spark tester
Useful and simple spark tester that gives a good clear to see spark. With hindsight, it might have been easier to check my twin cylinder motorcycle if I had bought two of them.

Not quite plug and play
It does the job quickly and simply once connected, but many of the newer suppressor type HT caps necessitate the removal of the aluminium nipple on top of the spark plug; if you have this type you are then committed to scrabbling in your boxes of bits to find one of the old type HT caps and another nipple, and this assumes that the cap that is on the engine isn't moulded in one piece with the lead. This could be simply solved by making the tip of the probe on the tester removeable in the same way that it is on a spark plug.
