Ergonomic, measures succession of phases in three-phase, performs RCD tests (this feature makes it unique in relation to the price). The only thing to be careful about is that the plastic surrounding the pins breaks easily....

The only cons are capacitors and amperes (obviously), it does everything else. It is handy and very fast to use. It cuts the cable in the wash and the legs have broken for people I know. As a professional, I have never met an electrician who doesn't have it permanently in their bag. It easily outperforms the classic multimeter, and the advantage of the 2 AAA batteries it needs compared to the classic 9-volt one is significant

When measuring 230 volts, it will be approximately +-7 volts compared to the multimeter and amperometer. The issue is that when the volts drop to 110 or even lower, it starts showing inaccurate readings. On a line that had 120 volts, it showed that it had 40 volts. I do not consider it suitable for professionals.

Excellent quality.

It is not a meter - but a voltage detector!
As such, it seems good.
Unfortunately, I had understood that it is a meter, which it is not. It does not have measurement accuracy.

For the price, it is very good... It has helped me a lot. And the lens is useful in the dark for the spot where you do the check

I haven't tested it enough on work to have an opinion, but for its price in relation to its build quality, it is very good, compared to more expensive models I had.

Very good instrument, there is nothing left to say that others haven't already said, except for the following, DO NOT LEAVE IT IN THE SUN. Within 20 minutes, the crystal screen stopped functioning and now it is just a decoration. I haven't received a response from customer service yet, I will update on how the situation develops.
Update: In the end, they told me that "replacement is not provided" for the corresponding damage, but I found it pointless to pay for shipping and repairs, so I bought another one, the same model, and kept the old one as a backup since the lights still work properly.
DO NOT LEAVE IT IN THE SUN!

Very satisfied. Very good product. I have been using it for about 1 year. It has phase sequence indication, continuous measurement, continuous voltage measurement, leakage relay test, front LED for mini flashlight (although it hasn't been needed), and it also functions as a test screwdriver - if you put the red tip in a socket, it will make a sound if you hit the phase. Excellent value for money.

It is a worthwhile product for its price. It measures currents, detects phases, has a check for relay leakage, detects errors in three-phase systems, for example, if a phase is reversed, it can identify it. It displays current frequency. It operates at 12-690V. It has an LED flashlight to see where you are touching the terminals. It requires 2 AAA batteries. It is suitable for both alternating and direct voltage. It has a bright indicator and an audible sound. The probes attach in a retractable manner as seen in the image, allowing it to fit precisely into wall sockets with one hand. It is a very good tool. I bought it for 40 euros including shipping within mainland Greece. I believe it is not the cheapest, but the best in terms of cost-performance ratio, as it is not a counterfeit product (it is quite sturdy) and it is a branded instrument.

Very good build quality. The voltage and frequency in Hz are displayed on the screen. It has an indicator light that shows the direction of rotation, and with this information, you can find the sequence of phases. By pressing the two yellow buttons, you can test the leakage relay. For its price, it is a very good choice
