Junk out of the box!
Junk out of the box! I had to repair both testers before they could be used. The test lead isn't crimped properly to the neon light. It was in two pieces in the package. I re-crimped and I guess it worked okay, but I'm skeptical about the tester now.It's cheap and you get exactly what you pay for.
