Worth the money, I'd buy it again
As described on Amazon. Worked right out of the box, batteries not required. Tested it on a lithium rechargeable battery and it worked exactly as it should. It is just a glorified test light but the digital voltage readout will allow you to determine whether the right voltage is traveling through your circuit, just because you get a light to illuminate doesn't mean it's the right amount of voltage, so this will help you through the process of elimination to decide what to do next. I bought it specifically to find out if my coil circuits to the spark plugs are all good because it's throwing out a misfire code.

The Test Light That Made Me Hate Electricity Less
I’ve always had a complicated relationship with electricity—mainly that I’d like it to stay far away from me. But this tester? It made me feel like a certified car whisperer. What I like: • The digital display made it super clear what was going on—no guessing games • The light-up tip is clutch for night use or garage shadows • The extended wire gives you the freedom to move without doing yoga poses under the hood • Polarity indicator made me feel smarter than I am • Bonus: it beeps! I like when tools talk to me What I don’t like: • Still not a fan of electricity, but that’s not this tool’s fault My final thoughts: If you’re like me and wires make you nervous, this test light is your new best friend. Easy to use, easy to understand, and doesn’t make you feel like you’re defusing a bomb. 10/10 would shock myself less again. Tip for buyers? Put the probe cap back on unless you want to find out how sharp that thing really is…

Great test tool.
Excellent circuit/fuse tester. Simple to operate and gives a very good reading of voltage on the large numeric display.
