Great, glad someone found you a solution. I am curious about your allen wrenches not fitting the airflow, that must be some small airflow or is it airholes like on subtanks and not slots? Let us know how those tank wrench tweezers work on removing the tank. I may get a set for when I need to fiddle with a hot RDA and I could use another ceramic tweezer, may as well be this one.Even the smallest of my set of allen wrenches is too large for the air flow slots. I've ordered a ceramic rda tank tweezers (tank wrench LOL) and a couple of other tools from Amazon. They sent me a text that they were delivered today. Now I get to change flavors without a mess! Thanks to everyone who helped me with their suggestions. It's good to have friends.................and knowledgeable ones too!
