Absolute must-have tool for DIY mechanics and troubleshooting
This 12-volt power probe is a must-have for any do-it-yourself mechanic. Iām still discovering everything it can do, but it has already become one of the most useful tools I own. Itās been especially handy at the junkyardāhook it straight to a battery and you can power electric seats, windows, and locks without tearing anything apart. Being able to test circuits directly makes diagnosing electrical issues much faster. Iāve used it to find shorts, identify broken wires, and quickly power components like locks, radios, and windows to confirm they work. It saves a ton of time compared to traditional test lights or chasing wiring blindly. The tool feels solid, works exactly as advertised, and is incredibly convenient for both troubleshooting and testing. For the price, you really canāt beat it. This is one of those tools you donāt realize you need until you have itāand then you wonāt want to work without it. Highly recommended.

Great for DIY fixing vehicles
I'm more new to automotive electric so this tool definitely was perfect for me. I was able to read the instructions and diagnose my cars wiring problem in no time. The light on it is very bright so that helped me in dark cramped spaces. It functions perfect for the price.

Works great and very cheap
Works great as a power probe! Wire length is very long. Easy to use hook up ground and test or send 12 volts to what youāre needing to test.

Works great and it's a steal at that price
Works as described, Works great. I needed a fourth, because my $400.00 test probe master kit was picked up by a lucky driver, before I could turn around and get back on the highway š¤Ø,the other snapped at the end of the tester(my fault) the other shorted out internally, definitely toasted the mini electrical circuit board (probably should of realized it wasn't for 24volts on a Volvo alternator). The other is peeling or dissolving to high use. My wife bought me an advanced, extremely complicated new test probe master kit that looks like it does everything a laptop with software auto program can and I just haven't tried it after opening it and staring at it a minute, I just didn't know where to start it navigate that beast, so sometimes, on certain jobs,the cheaper, not so complicated ones work great (yes all woman are complicated, but tools don't have to be);
