Yes...filling from the top is easy to do, but once in a while you'll get a little messy, either way you'll always need to purge whatever flooded the chamber by inverting and blowing it clear with a tissue or napkin handy, and on those rare occasions when I need to access the coil with a full tank it's easily sucked dry with an eye dropper or plastic nipple top bottle...but hey, that's the beauty of using Kayfuns...so many options to suit our fancy.
Exactly. I didn't get much juice through the air hole to begin with. But being new to the kayfun world, I wasn't really expecting any. It was very easy to purge it quickly and just vape on.
