pros: produto pequeno, fácil de manusear contra: escrito tudo em japones ou chines, não consegue entender nada. Não consegui medir voltagem em veiculos, so consegui usa-la em tomadas residenciais de 110 e 220. Correntes menores não consegui medir. produto meio frágil, não pode ser usada para rosquear parafusos, porque quebra. Read more
Reads live power even the wire is sealed, without pealing the protective cover.

the significance of 2 buttons unknown. Good handy tool, can do 2 jobs , detect ... Read more
Better than expected.
Doesn't use batteries!
Has a pocket clip.
It can detect energized wires by induction, without having to peel them or touch conductive parts (shows a small lightning bolt on the LCD). So it's probably good to detect the point where a power cord is broken.
Writing in the back of the wrapping is in relatively-understandable english!... Read more
-- does not needs any batteries for power source
-- line powered, so no worries about power source
-- lcd screen indicates which voltage is detected -- lights up all previous voltages upto the current one, this can be very confusing for a regular user who does not know about this, as all the voltages light up and one does not know what the current voltage ... Read more
Cheap can't tell what the heck the buttons/sensors on it are for OK it got here - looks OK but has Chinese writing on it by the buttons. You need to touch one of the buttons at the top for it to show a reading BUT which one does what? I jammed the metal end into the eletric plug socket (kids don't try this at home) and nothing happened. Then I discovered ... Read more
It's useful and cheap. You can check both AC and DC voltage. It has a display to show the voltage and doesn't use batteries. Not too much accurate. You can check phase and neutral in an electrical instalation. Checking phase you can read the voltage. Checking neutral you can see blank display. If you don´t need great accuracy it's useful. Buy it ... Read more
always handy as a quick check tool, good life saver in dangerous situations a little inaccurate, but otherwise good I always use these tools to check for live wires - never trust anything, I think they are dependable enough Read more
A Voltage Tester and screw driver. The display work fine and consider worth the price. Display not accurate. Even on DC power, it still show about 55 v - 110v. Wordings in are in Chinese characters. Nil Use this to test whether is there any electricity on the item and also as a screw driver. The result is not accurate. Read more
