Sinstar Automotive Circuit Tester 6-24V DC Multifunctional Test 12V Power Circuit Probe Tester, Car Fuse Tester, Short Finder for Continuity Testing/Trailer Light Testing

Works great, I just wish I had got one of these years ago

I recently purchased this Multi-function Automotive Circuit Tester from Amazon, and I'm pleased with its performance. The device is easy to use and has a variety of useful features, including continuity testing, voltage polarity testing, and short circuit detection. The built-in flashlight is a nice touch, making it easier to work in dark spaces.The tester is simple to operate, and the LCD display is clear and easy to read. The long leads (14.7ft) are convenient for reaching distant areas. I appreciate the 1-year warranty and 30-day return policy, which provides peace of mind.Overall, this circuit tester is a valuable tool for any car owner. While it may not be suitable for all AC and high-voltage applications, it's a great addition to any toolkit. I recommend it to anyone looking for a reliable and convenient automotive circuit tester.Pros:-Easy to use & Multiple functionsBuilt-in flashlightLong leadsClear LCD displayGood warranty and return policyCons:-Limited voltage range (3.5V-36V)Not suitable for all AC and high-voltage applications

Use this all the time when working on cars. Great to test circuits, bulbs, relays,… paid less than half the price of the “name brand” models and I can’t imagine how those ones could work any better. We’ll see how it holds up over time but it seems to be pretty durable.

A la verdad sale muy bueno y se trabaja con facilidad

I thought they would be too long. I needed another 3-4 feet on one project. Wish I got the longer ones. They do take up space in the tool box. They work great

Cool little tool to have, nothing crazy but easy to use

This tool makes troubleshooting so much easier. I have used it several times since I got it and happy with the results.

I haven't used it in practice yet but I tested it with a 12V source against a multimeter. This device reads 11.8V while the multimeter reads 12.21V, connected to the same source.With this device hooked to the same power source, I hooked the multimeter to receive power from it. I tested sending positive and negative to the multimeter. With a ground, the multimeter reads 0V and with power it reads 12.2V. Both are as expected.I'm giving it 3 stars because of the incorrect input power reading. I'm still going to need a multimeter to confirm the input power is correct before using it. However, being able to test if something has power or ground and being able to send power or ground with the click of a button will make this little device pretty useful. I'll update this rating after the first real world use.
