Review: Better Quality Than Expected - This tester is exactly what I was looking for without breaking the bank. I must say I was surprised after reading some of the other reviews. Came with all items pictured. The tester itself is straightforward and easy to use. The instructions included are helpful, but could be more detailed in explaining some of the more uncommon functions. I have seen some online videos with the use of tools similar to this. This tester does everything I need it to. It has a lengthy cord to use and you can attach to a 12v battery or a 12v cigarette lighter plug which is useful if using inside the car. It also has a long extension cable to add 20'. Everything seems pretty good quality. I am content with the price. The tip seems solid and pretty sharp to pierce the insulation on some wires. I was worried about the tip not screwing in, but that is not an issue. The included cap goes on first. This does not screw in. The tip then goes into the cap, and screws into the main unit. It screws in securely and didn't have any problems keeping it attached or coming loose. I tested some fuses, grounds and the battery terminals and everything works as expected. The tone on my device is kind of cheap sounding, but does work. The display is intuitive, and displays pretty much the same as in the video for this product. My only wishes were that the included bag was bigger to fit everything it came with. (Everything does fit, but you have to take time to arrange everything to fit correctly. The extension cable takes up the bulk of the room.) The unit itself is lightweight. Everything else has some "heft" to it and feels high quality. The unit itself is plastic and feels hollow. It doesn't weigh much, but doesn't feel cheap either. The rocker switch feels solid and responds with good feedback when pressed. Overall I like this product. I now know it will work for what I need it to. Hopefully this lasts me a long time. For the price compared to similar products, I would choose this model after having tested it out.
Review: Good tool at a reasonable price. Works well with ordinary cars. Well thought through design. - Works well, build quality is good, materials used are decent. The wires included are long enough to work on trailer wiring.

## Features

- 【Why Need It】The circuit breaker finder is mainly used to test the on-off condition of the automobile electrical system under the 6-24v DC voltage. When the fuse is blown due to a short circuit, using this circuit tester can help you quickly and accurately find the faulty wire and its fault point.
- 【Multi Functional】Automotive electric system is test for continuity. Test for polarity of a voltage. Check switches, relays and the on-off of diodes, fuses and circuits . Test for polarity of electric cables and plugs. Track and locate short circuits. Test for bad ground contacts.Do not use on AC voltage.
- 【Easy To Use】The circuit probe can be used to test and activate components in or out of the vehicle electrical system. Press button to “Positive”side with LED lighting RED. Conact the probe tip to positive terminal of tested component to active the component. If LED turns to GREEN with buzzer, stop testing and check the component if defective or not, or rating current of component is higher than that of this tester.
- 【Widely Applicable】The car circuit tester is suitable for the diagnosis of all 6V to 24V automotive electrical systems and can work well on cars, trucks, boats, trailers, motorcycles, and airplanes. The portable and ergonomic design of the automotive circuit probe is convenient for you to use in narrow areas; the 4-meter extension cord is helpful for mobile maintenance work; the clip with strong bite force is not easy to fall off, providing you with a better experience.
- 【High Quality】The circuit probe is equipped with overload power-off protection. If the current or load is too large during the power distribution process or When the current exceeds 7A, it will automatically disconnect to protect the battery and give a buzzer warning. With its short-circuit protection, you can test for bad ground contacts instantly. The insulation material used in this electrical tester has passed the CCC national safety compulsory certification, which is safe and reliable
