Couldn't agree more that it would be nice for something to just "work" once in a while.
Starts to feel like we're becoming the paying test bed for some of these things.
Everyone provides feedback, some changes are made, they get better (still not great), and by that time, there's something completely new that promises to be the "best" rendering the previous lines obsolete, and they become forgotten.
Also always seems to be that the liquid is to blame...
Different versions with different ohm ratings are typically available, why not different versions for liquid viscosity as well? Thin / thick liquid versions??
That being said, my revised C8's and ViVi Nova should arrive today, if they prove disappointing, I think it will be time to sit on the sidelines for a while and stick with carto's / atty's.
They may not be the best, but they're consistant overall...
