Heavy Duty Automotive Test Light Circuit Tester, 3-48V Digital Voltage Tester with Voltmeter & Dual Polarity Indicator, Electrical Test Pen with Stainless Probe for Car, Truck, RV, Boat Fuse Testing

Works great easy to use and worth the little extra.

I really wanted to like this tool. It looks very nice and well made except the reading for voltage is off! I like the reading for polarity, (I’d rather the green light be on for correct polarity) and the cord with probe cap is works well. The biggest problem is the voltage reading is not accurate. On a 12 volt car battery I get a reading of over 16 volts. So basically this for me is only a test light for continuity that will also let me know if polarity is correct. Review Edit. Seller offered me a refund right away. But since I don’t check my emails very often I didn’t see offer for around 2 months. I contacted seller to see if offer was still good. The seller refunded my money so I purchased another circuit testers. This second tester works excellent, I checked a battery that I had just charged it showed 13.1 volts. I checked the battery in my car it showed 12.3 volts. This tester appears to be accurate as the voltage numbers are within what I expected. I tested batteries with a meter and the voltages are within 0.2 between meter and test light. I would buy again from this seller as I’m very pleased with their after sale service.

This is a great tester getting just a little light showing up it actually shows you the voltage of what your testing. It is simple and easy to use. I really like this small convenient tester.

works great, shows actual voltage, good price

Great product. Easy to use, accurate, and my only negative comment is that I wish the red lead was a foot longer.

Works as advertised. Build quality if ok for the price.

Great product, amazing price

Works well. Easy to read
