The stick PC itself is great; it's relatively fast with plenty of RAM.  Runs Debian flawlessly.Unfortunately it's all ruined by one critical design flaw - the device spontaneously reboots if the input voltage falls below 5.2V, or current below about 3A.  This is far outside the MicroUSB specification; they provide a proprietary power supply with a MicroUSB connector, but it violates the specification significantly.This means if you ever try to run it with a different power supply (ie. in a vehicle), the machine is essentially unusable.Given the power requirements, the only appropriate choice was USB-C (rated up to 3A), preferably with power delivery.  I note that their larger units now feature USB-C ports.If you're planning to only use their included power supply, it's a great little device.  If you're expecting to take it with you and run it off any old USB power supply, you're out of luck.Update (2022/03/21) --PC powered off randomly a few nights ago and wouldn't power back on, no matter which power supply I tried.  Support was helpful and offered to repair/replace it if I sent it back, but since I wasn't able to boot the machine and wipe the data, I wasn't comfortable sending it out.  I sent photos of the destroyed unit and they weren't willing to replace it, which is reasonable, but disappointing; all in all an expensive mistake.
