Great Tool!
A very simple tool that picks up on voltage quite easily. The length of the wire is well sized for most cases. My only complaint is that the rubber warp on the handles of the ground prong managed to work their way off rather quickly, but that didn't affect the functionality of the tool. Definitely worth the price point and has helped me diagnose many automotive electrical problems.

High quality, cheap cost. Get this one. Worth it!
This circuit tester works great and is really easy to use. The lights clearly show positive and negative polarity, which makes checking things quick and simple. I’ve used it to test wiring and battery voltage on my vehicles and it’s been very handy. The long spring wire and big alligator clip make it easy to reach around the engine bay, and the sharp probe helps get into tight spots. Solid little tool to have around if you work on your own vehicles.

Lot of good uses for a good price.
Great basic tester just to check for voltage, works great to tell you the voltage of a battery (even 9V batteries) , will read out voltage of a car battery standing or running, helps determian if battery or the alternator is not good .

Very useful and easy to read
This automotive test light is very handy and easy to use. The digital LED display is clear and makes it simple to read the voltage at a glance. I also like the dual-color polarity indicator, which helps quickly identify positive and negative connections. It feels solid and works well for basic automotive electrical checks. The probe is sharp enough to test circuits easily. The only reason I gave four stars instead of five is that the cable could be a bit longer. Overall, it’s a useful tool and a good value for the price.

Meets my requirements...
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.

Fácil de usar, específico en cuanto a la polaridad de la corriente (verde o rojo) y sobre todo indica el voltaje que llega al punto donde se prueba.
