I have a pico istick 75w and I've been using a Melo 3 tank. I vape at 20w and the thing leaks like crazy. This is my 3rd or 4th one and they have all leaked. I don't know if it's because I chain vape, or what.. but it's a real problem. Any suggestions on a new tank that will not be as prone to leaking? I've been vaping since 2010, but I don't experiment much. I find something I like and stick with it. This is my first "mod" with a larger tank. I was using an ego battery and aspire tank before this. I've had this setup for about a year, and love it.. but my only issue is the leaking. It's driving me crazy. Any advice would be appreciated.
