Well, this is very nice single coil - direct lung - flavor chasing atomizer. This atty si produced by GeekVape. Very good for flavor and decent vapor. Well what can I say? All pros you can imagine - easy build making, great flavor, awesome filling. All fits as it should. But my piece has problem with very tough liquid flow - so i broke one glass. I do not know how to make it more soft. But at all this is MUST vape atty.
