KAIWEETS 0.8V-100V DC Smart Automotive Test Light, Buzzer Circuit Tester with Sharp Probe, Bidirectional Voltage Tester with Flashlight, Electric Test Pen for Car Battery Polarity Continuity Fuses

This item is great. Very well made and works great. Can’t test connections anymore without it. Very convenient and impress on how it automatically switches between voltage to continuity

I love this new tester; much more convenient and feature full over my old light bulb 12v tester. I am debugging an electrical issue in a mobile home and I am leaving it in the engine compartment (connected to solid ground) for quick voltage and continuity checks.

For a test light it does work good and easy to you in the field

Nice good working tool, and comes with a zip up case

Works good, backlit, measures to the 100th

Does what it says it can and easy to use !

Delivered the next day after ordering; pack well for delivery; instructions included; tested it out and works great; a great little tool to use in many ways; comes with a small bag to store it;

More than i know like it

10/10

Great handy tool to keep in your vehicle.

Great product. The point is very sharp. For some use cases the point maybe too big such as interior fuse box of car. You can use a safety pin as a work around. But

I read ALL reviews. Out of the box, the ground clamp sleeves were slipping off. So, I improved this by adding black and blue heat shrink. Refer to my photo. The blue heat shrink being shorter acts as a “locking” collar over the black heat shrink. Note the fold back on the ground wire. I also moved the probe tip up the cable and since I was at it, put red heat shrink on the exposed shank of the probe. Moving the probe tip up the cable curl improves tip retention naturally due to the looped coil spring tension. This probe tester is for DC use only. Do not use it to test AC power in your home. I tested 1.5 volt, 9 volt, auto 12 volt and 24 volt batteries. The readings were fairly accurate when verified with my Fluke true RMS multimeter. The ohms readings were off but one would only use this probe to establish continuity. One would use the multimeter for serious, accurate, troubleshooting. This probe is a step up from the DC probes with the simple LED or incandescent bulb in the handle. I have one of those in each of my vehicles. Store this in your vehicle in the trunk but not in glove box. Heat in the car during summer can be excessive. Also remember to change the AAA battery once a year. If it leaks, it will make a mess on the pc board in the battery compartment. I do this at Christmas time for all battery devices including smoke detectors, CO sensors, battery powered clocks etc… easy to get into this habit once December rolls around. This unit is good value for the money. Comes with a zippered case. Multilingual manual, AAA battery. I wouldn’t leave my expensive multimeters in my vehicles but with this price point and functions, this is a great little unit. The hold function is nice as well for those times probing under the dash connections don’t permit a viewing angle. So, overall, I’m pleased with this unit. Thank you.
