WINAMOO Upgraded 3-72V Digital Automotive LED Circuit Tester, DC Voltage Test Light with Voltmeter & Portable Spring Wire, Vehicle Circuits Low Voltage Light Tester Pen with Sharp Stainless Probe

I love this test light

Muy buen producto

Digital probe, same as always.

Very nicely made, especially read out easy to read. Excellent for the price

Purchased item to help with my auto repairs.

Thought this would be good for Auto and other electronics projects. When I opened it I tested it on my laptop power supply, 19.5 VDC & 3.3A max. I got the correct voltage reading for a moment, fluxuated for a moment, then no reading at all. The power supply went into a over-current condition then cut off. I did reset after a few minutes of being unplugged. So the tester must have been drawing more that 3.3 Amps just testing the voltage. I cant see this tester being useful for any low power circuit testing but great for Auto testing. I took off the 1 star because it is NOT good for also for testing other 3-72v DC wirings and circuits. The product is well made and seems to be a quality product. - It would have been nice if it came with a case to put it in.

Works well. Not complicated and that it shows polarity is nice feature.

I like that it shows voltage as well as continuity

Right out of the box, it worked as expected. Bought two more for friends...!
