Completely and utterly failed product, do not waste your money here. I used it to measure the consumption of a Toyotomi dehumidifier with min/max power 350/620 watts and it showed in high mode that it consumed over 1000w... I switched it to auto and low mode and the reading on the stupid meter was over 500w. Finally, after an hour, I checked the clock and the consumption was around 350w/h while it was showing over 500w/h. It's a complete joke, especially for a supposedly German company

The screen may not be anything special, but its measurements are extremely accurate. It shows Watts as well as Power Factor and doesn't label VA as Watts like many cheap meters do. It keeps the kWh value indefinitely even without a battery and correctly calculates the total consumption and cost. I have trusted it for many years.

It has many functions and seems reliable. One major drawback is the screen, which not only does not light up, but also, due to the fact that it has a double glass, makes the numbers/letters appear "double-blurred"

Mediocre because its screen is terrible. It lacks backlighting, the letters are very small, and the viewing angle is also very bad. You can't even see properly straight on, let alone at an angle.

The screen is literally garbage.... and since smart devices - sockets for smart homes have been released, it was a mistake to buy it from the beginning... okay, it's useful but the screen is very difficult to see if you look from an angle or simply the lighting is not good
