I'm going on 2 weeks now with my first e-cig- a Halo G6- and I'm very happy with it. Can anyone comment on the quality of the Halo cartos vs other brands/types? I've had no problems with them but since they're the only ones I've used, I'm starting to wonder if I should try any others. I'm assuming any other 808 cartos will fit? I've read the many threads about carto recommendations but not how they stack up against the Halos.
