First off I don't think it's the hardware that is issue but what you are purchasing is a development environment here.  Documentation is horrible and NVIDIA tutorials often don't work and you are forced to search the web for working 3rd party documentation in order to do basic things like NVIDIAs own tutorials. Be prepared to see Over Voltage warnings! a lot.  Yes that's with the supplied power adapter.  NVIDIA's failing on this product line is in making absolutely every step painful and time consuming for the new indoctrinated AI wannabe.  There seems to be some reasonable support on the forums but as to why their documentation fails that is baffling.  Best resource found for this device and its software I have found is on GITHUB. Basic things like downloading NVIDIA apps for the device fail following their step by step instructions. Even OS images seem to be an issue for some on the forums. HINT Use SDK on the recommended Ubuntu bare metal install to flash unit or suffer.  Some things that should be simple just don't work!
