On the vamo threading.
It DOES have both ego and 510 threading BUT some ego devices do not fit well as the ego threading is sort of recessed down into the top of the VAMO. Some ego devices fit without an adapter and some do not.
I ALWAYS leave an ego/510 adapter on mine. The threading on a vamo is brass which is a soft metal. There have been quite a few reports on the forums of stripped or otherwise damage threading on the vamo. I put the adapter on and just leave it there (so screwing something into the vamo threading ONCE) then I attach all my devices to the adapter. I just feel it cuts down on the wear and tear on the vamo threading protecting it a little bit.
