 +For end user, there is no difference.
 +
 +COMFAST CF-EW72 V2 is known to be produced in two variants (**not versions**):
 +  * COMFAST CF-EW72 V2 with MT7621AT and separate DDR RAM chip onboard.
 +  * COMFAST CF-EW72 V2 with MT7621DAT with integrated RAM and no DDR RAM soldered chip onboard.
 +PCBs for both variants seem to be same. Firmware works for both.
 +
 +COMFAST CF-EW72 V2 known to be sold both in unpainted cardboard box and colorful glossy cardboard box.
 +I guess, but not guarantee that colorful box is for new variant equipped with MT7621DAT SoC and no RAM chip.
 +Seems that devices also have different factory labels.
