I don't know if this has already been asked, but I can't find it....does anyone know if the atomizer "knock off" heads with the little cones on top will fit the real vision vivi tank? I like a new atomizer every few days and really don't want to build myself. I notice that DHgate sells knock off heads for only $1.00 each but they all seem to be the ones with the little pointy top. Will these fit?
