simply solution for testing spark.

Spark tester, September 27, 2014
This is a great spark tester. Only gave it 4 starts as the spring keeps popping out of the clip.

OTC means what, September 26, 2014
Ordered two, lost one already. Gets used a lot, hasn't broken.

Good to have for a quick test, September 23, 2014
It's ok. Spring keeps popping out from the clamp. Good to have for a quick test.

Tester works great.

Good but not great, September 13, 2014
This product operates very well, the one drawback is the clip is not very sturdy other than that it does what it is supposed to do.

Inexpensive and effective, September 11, 2014
Works as described. No more screwdriver spark checks.

I love it, September 9, 2014
Great product
