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

Very easy to read. I like the led light with it too

This LED testers is easy to see and works great fir testing fuses.

Very good price as product works very well. Needs to have optional hard plastic case

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.

I like it just as well as my snap-on test light..at a fraction of the cost...

If you are doing any electrical work on your vehicle, this tool is a must. Just find a good ground and you're set.

great

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