Visually good, but the description or circuit diagram is missing. Unfortunately I didn't see this before ordering, otherwise I wouldn't have ordered at all. I asked and am curious whether they can send me a circuit diagram. If not, accidental destruction cannot be ruled out and the device cannot be used by me. As a schematic, I was sent a YouTube video of an absolute bungler that talked about Frequnz. At this point I finished the video and asked how someone could shoot and publish such garbage. In any case, after pointing out the unusable video here, my money was refunded. In any case, the values ​​on the display are said to be very inaccurate.

It worked for a day and it doesn't show anything anymore

Everything great!
