WINAMOO Automotive Test Light with 3-48V LED Digital Voltage Display, Auto Circuit Tester with Voltmeter & Dual Color Polarity Indicate, Electric Test Pen w/Stainless Probe for Car/Truck/SUV Checker

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.

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.

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 .

WINAMOO Automotive Test Light with digital voltage display works as expected and does the job. It’s accurate enough for basic use and the display is a nice feature. That said, it doesn’t have a heavy-duty feel—the wiring feels more plastic than rubber, and overall build quality is on the lighter side. For occasional home use, it’s perfectly fine. I wouldn’t expect it to hold up long in a professional environment, and I could see the cable getting brittle over time if it lives in a toolbox. You just have to be realistic at this price point—it’s cheap, and it performs like it. I’d call it a 3-star tool on quality alone, but for the price-to-performance, it earns a solid 4 stars.

Very nice test light at a great price. Volts test same as my good test meter.

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.

Worked as it should, I am very happy with my purchase

Not only check continuity but also determine the automotive line voltage. East to read, simple, and neat

Muy prácticos

tres bonne affichage

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.
