ive been using my protank for almost 2 weeks now and started getting a bad gurgle juice in my mouth and a leak. i was trying to figure out what the deal was and i remembered when i first started using it i kept it full and it never got about half way. i was at a dance hall when i started getting insane amounts of juice in my mouth so i tried blowing it out threw the bottom and realized all my juice is gone. yay.... i come to realize when the tank gets low its starts to gurgle and juice gets in your mouth so now you half to keep it some what full. is this a draw back? yes!
100% although it preforms good and the juice tastes good, once you hit that low point and start to get a little gurgle you have to fill it back up to avoid it. its sad that a nice tank like this cant go through a full tank, it just cant. unless theres another fix that allows you to vape a whole tank with no gurgle or leak, but i think its more of a design issue. so if you have a gurgling pro tank just fill it back up, you might have a little gurgle but it will go away at least with my experience. i hope this helps yall that have one.
