...because they suck!! Im worried that juice is leaking under the post. I have a Vapor4Life ego. Luckily im obsessive about it and constantly unscrew the mega-cart to check. I find juice on top of the post a lot of the time after I put a few drops in the cart. Is the juice going to leak under the post and hide under there? Is this going to ruin my battery? How would I clean it out? aghhhhh!!! Luckily RoccoV has been nice enough to offer to send me a dual-coil cartomizer. I can't wait to get my tank back on my EGO and experience that beautiful VP and flavor and the LACK OF LEAKING!!!
