Let me start off by saying I apologize if I'm somehow doing this incorrectly lol. I started vaping about 2 months ago, and made the sad mistake of starting with a Blu brand starter kit. I was unhappy with that so did a little more research and decided to try out the Joye 510, which I've definitely been diggin. After a week or two of vapin that and more research, I decided to give the 510 cartomizers a try as I was under the impression there would be less refilling necessary. According to reviews I've read/watched, these things should hold about 20+ drops on a refill and generally vape for a good hour or more. Though they vape/taste great, I'm finding that everytime I try to refill, i can only get about 6 drops in before it starts leaking out the battery connection-end. I know I'm letting it dry out completely because I'm waiting until the juice flavour is gone and pop the white rubber cap to check the filler which appears dry and white. Could this somehow relate to the e juice I'm using (18mg hawaiin punch, 24mg tobbaco from awesomevapor) ? The methods I am using to refill are popping the cap and dripping along the sides directly onto the filler or dripping through the hole in the battery end in which case it leaks out the opposite side still after only 5 or 6 drops...Am I doing something incorrectly or what? any help or suggestions would be genuinely appreciated...i feel like a complete idiot not being able to figure this out. just wana get the most outta my cartos/juice. thanks.
