KAIWEETS VT501 DC Voltage Detector for Cars, DC 0.8 V - 100 V, Total Length 78.7 inches (200 cm), Power Supply Check, Car Voltage Circuit Tester, LED Probe, Conduction, Diagnostic Tool, Black

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

The voltage reading is accurate. Continuity test is also working with a buzzer. Te device works with a pencil battery. Very cute bag comes free. Extremely satisfied.

Good product

Very good

Worked good for only 2 months. Display blurred.

Good product with changeble battery.

Very slow this product

Price is so high box was cheap

今後も何か使い道があるかな・・と思って、良さそうなものを購入。 いろいろ計測できると、楽しいし、安心して作業できます。 取り付ける装置の値段と、取り付けを依頼せず、自分でやることを考えて、保険の意味を込めて、このくらい購入しても後悔はないと思います。

Works great And easy to use

super

This has been a good tool so far. Sometimes you can’t do a job with a multimeter easily and these pen meters while basic get the job done Readings seem accurate when tested against a known meter This often gets taken from the draw first as it’s so simple and fast to use for work on machines. Continuity beep good and loud for use in noisy workshops My second Kaiweets product and they offer great value

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.
