So I have a provari mini and ordered a hh.357 atomizer long barrel.. I have about 30 juices coming in for the wife and I. Now I have dripped for my first time with a atty few days ago. No leaks, no harsh burning taste. Couldn't say taste was better than my tank (mini nova) since I used a different juice. But I'm sure after the break in on the .357 I'm hoping for flavor. Going to strictly drip at home and tank at work or anywhere I go outside of home. Now I heard I should get a 510-510 adapter? I have a drip shield coming. Now I see there is open and closed adapters? What's the need of this adapter? Do I have to have one? I didn't use one on my joytech 2.5 atty. Maybe had a faint drop on batt connection but I wipe with a q tip.. best place to look. Heard or may I say read that a lot of them have threading problems. Sweet-vapes is 6 min away and have some I think.
