Rebuild my atomizer yesterday day for the first time . . .I was cleaning my tank when I notice the silica wick was kinda dark so I pulled of the air canal and the silica wick looked nasty I didn't have n e kanthal wire handy so I used the same wire that was already in the atomizer heated it up and wiped it clean then I used cotton stretched to my desire length and twisted for desire thickness I must admit rebuilding it was quite fun actually now my flavors are superb and vapor production has increased
