Got mine today and I was influenced by the hype to buy it.So far it seems to have some gurgling issues and some inconsistent draws,You do get Nice airy vapes mixed in with those thick bubbly flooded vapes.Then had some minor leakage after I filled it to the top line and gurgling so I had to syringe out the juice and gave me a chance to see how its put together.The stem is threaded down where the juice is, why??? If I lived in a house that was halfway underwater I would want my windows to be above water,They just had to be different than the vivi.Also you know when you have your vivi tank sitting for a while and the first toot is that cloud of velvet well, this is gurgle city.I also don't know if I'm a big fan of the top silicone cap because it is big and moves a lot while taking of the mouthpiece.Yes I am comparing this to the vivi nova and thought it would be the same as the vivi but better,From what I heard.This is my first day using it and I need to figure out how to eliminate or fix the gurgling issue,On the vivi is usually is the top silicone cap,so I don't know if it is that.It does vape excellent in between those issues better than the vivi nova but the vivi is more reliable it seems.
