Not throwing stones at any product and/or company but what's the story with these sub ohm clearomizer products? I have four, two old and two new, different makes and models and everyone of them leaks fluid from the airflow slots at the bottom. No they are not over filled, have been rebuilt with brand new seals, atomizers, but nothing helps. I go all day to only a few minutes and go to pick up the mod only to get my hand covered with juice. Some are top fill, some bottom but it's a mess when I'm in public! What's up!?!
