I haven't had any luck with the Vision stardusts either. I have used 10 of them, low ohm, reg ohm, just always muted (& a stiff draw).
I've used them on a Provari, iPro, & ego 1000 mah - just all muted.
The juice I use is (mainly) Halo Tribeca & Prime 15.
My favorite is: ce2 Vision extreme clearomiser in 2.5 ml (the 2.4-2.6 ohm ones). Yes, they use up juice faster, but the flavor is great (& worth it to me).
