Just got my vision eternty today,had a quick read of the instructions,put it together in dripping mode and put the recomended 40 drops in.Unfortunitly about 10 drops poured straight out the airhole at the bottom!.Had a cleanup and had a toot,WOW huge amount of vapor,throat hit almost hurt (it was that good),im used to the vision stardusts quirky leaks so a bit of juice in the bat well wont worry me,probably stick with my ViVinova for out and about but this will be my new burbon drinking buddy, 7/10 for me
