I would give this a 0 if I could. First, it has no body - just a sandwich panel on which everything is visible. Second, he died after the second use. Third, the written instructions are so poorly written that they seem pointless. Fourth, I followed the instructions for setting the language to English exactly, but stayed with Chinese. Fifth, this gadget is not intuitive - you need to be a trained professional to use it. I even watched YouTube videos on it, but they were unnecessarily complicated too. I bought this to test the performance of various wall adapters I have. Sometimes it showed power in watts, sometimes nothing (although it did show other readings). It shouldn't be that hard. Finally, it's ridiculous that the USB-C cable only plugs in one way. One of the reasons these cables are desirable is that they are unidirectional. Rarely have I been so annoyed about a product.
