It will definitely not fit in the tank that comes with the revenger x. Two completely different styles of coils.
I've been using the Revvo for about a week now. It took me a day to figure out how to properly fill it so I could stop some of the issues
@sarcky was talking about.
The main thing you have to learn with it is how to properly fill it. It works best with unicorn/gorilla bottles. You have to:
Squeeze the bottle slightly while still holding it upright
put the tip of the bottle in to the pin while applying pressure to the pin
fill slowly
release pressure on the pin and finally
release pressure on the bottle to suck up an residual juice.
The reason people have issues with it is getting juice on top of the coil, causing the pops into the mouth. Once you fill it the right way, these problems go away
