Works well. Fast shipping.
Received product as described and well packaged. Product is the newer model fo ZY1280 series, ZY1280M. The delivery (standard) was pretty quick, as it took a meager 7 days from China to Finland. Measured from USB-C port that ZY1280 takes about 0.02A of current while screen is on, 0.012A with screen off and 0A when supplied with ext-pwr Measurements seem accurate and the graphs come in real handy Menus are straightforward and don't take long to figure out, on this model/firmware the graphs are "hidden" behind a menu. Here's more details on menus and how the buttons work in each mode: pastebin com / JxUkkZfR Highly recommended!
