Review: Good tool - Works great. Only needed a few times, but these save a ton of time in diagnosis
Review: A rare bargain on a great tool - I worked for Cummins Ct for 45 years I wish I had one then. A test light only shows if power is present. This shows if power is present and how much, it is a great bargain saves hooking up multi meter. I have told others don’t wait buy one

### ⭐⭐⭐⭐⭐ Good tool

### ⭐⭐⭐⭐⭐ A rare bargain on a great tool

### ⭐⭐⭐⭐⭐ Meets my requirements...
*by J***A on December 23, 2025*

Works great! No need to drag out the multi-meter for simple automotive testing. Shows voltage up to ~40 volts DC, with green light to indicate correct current flow, or red for reverse. Has ~8 in long insulated probe, with ~3 ft spring cord with an attached alligator clip that allows a relatively large area for testing without resetting the clip. Read-out is bright and easy. Can't confirm reliability, only had it for a month, but appears to be fairly robust. Only cons, the cord while not flinmsey by any means, is not as "stretchy" as I would like, but I suspect this will clear up with use. Also the alligator clip could be larger to facilitate easier clipping to bolts for better ground,(I know, being picky). Due to being 10 - 12 inches long plus the spring cord, this tester is definitely not shirt-pocket friendly, but I would definitely recommend it.
