Great little simple tester
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

Very solid product
Worked and fit into even the tiniest car fuse slots in which my multimeter probe was too big to fit. Very simple and clear operations and instructions.

Perfectly fine and easy to use.
Perfect. A fuse blew in my BMW over the winter due to some frozen windows. Rather that take it to a garage I did some research a figured out the fuse was the problem. It was not easy identifying the fuse and I did not want to take them all out sone at a time. Porsche c this and it allowed me to identify the fuse within 5 minutes. Money definitely well spent.

Well made and works well
Excellent product. Well designed and well made. Comes with a zippable case, instruction manual, and battery. I can't see any - / + signs in the battery compartment as per instructions but the battery fits with the - at the spring end as you'd expect. The buttons have a good, firm action and the display backlight works well in dark places. The hold feature is very handy if you need to go write down readings. Much easier for checking various batteries and circuits in a truck/trailer combination than a multimeter - no need to find a flat spot to balance the meter. Great to have with you as you travel.
