It doesn't mention on Halo's site if it is ego or 510 threaded or what. Maybe someone with experience can chime in? I know they will fit on regular ego batteries. But if the threading is compatible then yes, you would just attach it and drip a few drops of liquid in there, place drip tip on top, then puff away. After done sampling just blow out any extra liquid and you're on to dripping your next sample!
