I received a gift that I had no idea what to do with so I turned to Google and YouTube. It's the strangest rebuildable tank I have ever seen. It's a German Still Vapor. It uses an SS mesh strip and has four Stainless Steel cables that drop down into the tank. After watching a "Todd's Review" I decided to give it a try. It is awesome! It wicks as good or better than any RTA I have and absolutely no leaking. Sent from a Galaxy far far away!
