i love my gobin, i got it a few months back and my only issue is filling. i can't use a glass dropper, i found a blunt syringe works but is slow and i don't like carrying it when i am out and about. unicorn bottles work but it seems to trap air and push the juice out. i tried holding the talk firm and unscrewing the top but when i screw the cap back on it pushes the juice out of the air flow. so my question is, is there a compatable top filling cap that will work when i am out on the town. i have heard i some rta's work like that. most kayfun parts work with my orchid but my goblin performs so well i want to use it all the time and smash my sub tank mini to pieces. thanks for any insight.
