JFC! Mine's been on it side in my pocket plenty of times with the JFC open & it doesn't leak
Both are great tanks, they're both completely different beasts though. The Aromamizer is more versatile with it's multiple decks, tank capacity's & airflow options. The Profile RDTA I run in dual coil mode & it's top-level, I tried out the mesh & couldn't get the airflow right with it, so I gave up & brought another Profile 1.5 RDA
I have the V2, leaking seems not to be a problem in most scenarios tbh.
The earlier Steam crave tanks did leak a bit though.
Can't say I've experienced any with the V2.
