I bought the first one and tried it to see how it works. I used a Meanwell 5V 60A LED power supply as I have been using USB anti-miners and wanted them to run at full power all the time. Flawless, except the Raspberry PI barely kept up. The second one I bought was completely worn out. The capacitors are half out of their sockets and are bent and touching the metal. Some USB ports lost a lot when you had something plugged into them and lost power unless you pressed on one side of the connected device. Blackboard. So some of the UBS ports were not working. Looks like their machines broke and passed quality control. It consists of 3 circuit boards. 2 - outer shell. Traces, it seems, of aluminum. The components used look standard and have nothing special about them. I can buy more IF and IF I get my second RMA/DOA department up and running again and it looks like my first.
