It's not a good product, it's a pity that I spent money on it.

Previously, I already purchased from another supplier and used the device, there were no comments. The other day I bought the same one from MEGEON. To say dissatisfied is to say nothing. The device was purchased for professional use. Current measurement accuracy is disgusting! The error reaches 50%! I am enclosing a photo of checking the current measurement with a verified calibrator: when setting the current to 20 mA, the multimeter shows 13 mA!

Pros

Build quality.

Cons

Current measurement accuracy is extremely low and not suitable even for amateur use. When measuring a current of 10 mA, the error is about 50%! Perhaps I came across an uncalibrated device, I had already used such a device before, there were no comments.
