I bought a 4.5ml Vision 510 Clear Clearomizer tank from DiscountVapers.com... and I can't figure out how in the world to fill it! The mouthpiece doesn't look like the one on their site which is fine, it's a round tip. That comes out easy. This thing is a silicone cylinder. When the mouthpiece is taken off, it looks like a hole with filler material in a circular shape with a hole in the middle. I've put fluid directly in there. NOT right. It was like filling a regular atty with fluid. Cleaned it out. Still burns when threaded to a battery (and it won't thread tight... stays loose). I've got needle tips, but how in the world and WHERE in the world do I fill this bad boy?? Sorry... I feel like a 'tard, but I spent $7.99 on this thing and can't find any info on how to use it
. Thank you!
