Very poor speed on microSD, no Fedora support (which would be cool with the good video graphics hardware they have installed) due to strange hardware options, no wifi . There seem to be power consumption issues even when using the 2.5A power connector when using a video out and USB at the same time. There's a good overview if you search the web where power consumption and SD boot issues are discussed. It's obviously better to use EPRoM, but I don't want to invest in a lackluster Pi clone. 2 stars because it works if you disable everything and just want Armbian, but it's a waste of good video hardware.
