Hello guys i bought three 5 packs of .15 ohm nickel coils for sub tank mini. Using on hana dna b4s dna 40. So far i have tried three of the coils any were from 410 degrees to 480 and 20 watts to 30 watts. Result is the same very little vapor at all Flavor taste dry. any have any problems or suggestions with the coil heads. These are bought coils from the same time vapor shark not made my self. I havent had one problem with any of the kanthal occ coils for this tank. At 4 dollars a piece is realy making me mad at the momment. Thanks guys.
