Arrived quickly and in great condition. It's been turned into the main board for a cyberdeck build. No problems and has worked well with mobile power from both a pisugar2 pro and an x708 power pack (it's currently powered from the x708). It can run a bit on the warm side so I've got an oversized heat sink and the additional fan cooling from the x708 which seems to keep temperatures down a bit. Noticeable improvement in performance over the pi3b which I've used for most projects to date.
