I still have one in the package, opened 2 for now, they really great when they work, beautiful vaping experience, but what good is it if it leaks, I obviously can't leave the house like this. I had a vision 3.5 leak all over my pocket yesterday but that was my fault because my kid was jumping on me and the cap came off in my pocket. Thats a controllable incident, this is just random leaking. Plus with the vendors taking the stance that the only warranty is DOA, 10 dollars a pop for a dud is too much. after the stone tank disaster(I just threw out 2 stone v1's that were supposed to have innards and one was defective from day 1), and now this, its hard to justify going with other than what is known to work. i been using the 3.5 L visions almost exclusively now and they don't leak, they just gurgle because of a crappy vent design which the 1.2 L don't have but then you fill those every 10 minutes.
That really sucks. I haven't refilled mine yet. Or, for that matter, even opened/unwrapped the other one. I'm conflicted. I really wanted to be able to use my ego-W pencaps to be able to clip it to my lanyard at work. I may just end up ordering more of the 2.5ml Vision tanks like Lord Davon suggested. They don't crack, like almost all of my 'Stardusts' have, and I couldn't use the pencap with those anyway.
