Product arrived with all components intact. Have not tested yet.
The product came with an 500A option (which was not mentionned and not possible to select when ordering). However illustrations of the description show a display with a 0.1A resolution in current. I have strong doubts (I can not make tests soon) that the dynamic of this products ranges from 500 to 0.1A. The lower limit is probably achievable with other Holzer options such as a 50A max current. If these options cannot be sold by the supplier I suggest a much clearer description of the product on the website
