Pobre para medir 480 no funciona en uso industrial No vale la pena comprarlo. No aguanta duró dos días

Works fine for me havent had no problems yet

Accurate and ease of use

The functions work as expected. Detection wise, theres a sentivity setting for NCV. The issue is the probe sensor/antenna is probably not at the sharp pointy end, and behaving more like it is inside the unit. It will work detecting voltage for sure in an electrical socket or wire, and sensitive enough to differentiate between 2 adjascent wires which is the live one. However, the dealbreaker for me is the probe color scheme. The main Amazon photo shows a monotone color scheme for the probe. That is - the red probe is entirely red. But what I received was like the last photo in Amazon which as stupid and dangerously confusing black-red-then-red at probe coloring. Whats worse is the cap follows the long handle. So when you take off the black cap, the end tip is red! It is so easy to confuse black vs red! Did the designers never use the tool? See photo.

Awesome little tester! Simple to use and totally accurate!

works good

These devices are powered by batteries, but in order to put the batteries in you will need a Phillips head screwdriver to remove screws to open the cover so you can put the batteries in.

Nice product

For the wiring test, it is excellent. Give clear indications of what wrong. The non contact voltmeter(NCV) is worthless. It has only gone off while plugged into the outlet. Still 5 stars though.
