i guess you bought it used? or did they change the wicks?
im not too experienced with the ceramic but try to tilt and keep the wick really wet when you vape. you can try to change the coil. but im at a loss on the ceramic, im a mesh guy. lol others have said it takes a bit for the ceramic to break in and start wicking properly.
the ceramic wicks are used indefinitely, and mesh is used till it doesnt work anymore.
