I am fairly new to vaping. I just bought a eleaf Istick 30 wat with a Kanger Protank 2 and its leaking a little bit at the 510 connection. Will this mess up my new IStick? I tried the fix to add an extra o ring and it didn't work. Now I get a slight burnt taste sometimes. Is there any other suggestions? I do plan on getting another tank....Maybe a subtank. Haven't tried the sub ohm thing yet but I wanted to explore. I also wanted to explore dripping. I haven't found the perfect all day vap so i am into trying different juices and I've read that dripping is a good way to find it.
