I was impressed up until the part about having to use their flash/update files. Personally I'd never buy a dongle where you had to wait on the devs to relase an update, when others are available and can be flashed easily using hex files from the net.
Given this info, I'm swaying more towards the X3Max...I'm not a fan of having to use their custom util to flash either (in case it doesn't support things in future), however it's nice to know if there was a new 'Hermes' or 'PL' build tomorrow I can update things myself.
