Arrived in an antistatic bag. I didn't notice overheating when using it for long periods of time. The soldering on the PCB is excellent. The module measures 63.7 x 27.7 x 12.6mm. All inputs, outputs are solid and well made. Works fine from 9V to 36V input and running cold under max loads. There is a 5,5 x 2.5 barell connector for powering the module. The USB-A output voltage is stable at 5V. Only drawback is that the edge of the USB connector is at the same level with the PCB which makes difficult for the USB connector to stick out seperately when is put in a casing.
