the cap on a cyclone afc is rock solid, you can pick the whole mod up swing it around and handle it just holding the atty cap and the cap isn't going to move or adjust or pop off easily but it's a bulky cap
I also have a few other atties with orings that are rock solid,very little chance of movement but there all bigger bulkier thicker caps. for a thin sleek atty I think screw on is the best way to have a solid cap, the tiny orings used in a thin sleek atty just don't hold tight enough for my abuse.the v2 is def better than the v1's but twice today I pulled my mod from my pocket and the cap came off, totally worth it the way it's vaping and truth is it's not very loose, but I like my stuff screwed together tight enough to stay locked together as one piece in use, plus the positive airhole location of a screw on cap is great,just more trouble free even with abuse
