Ok so I have an a7 and a smok rda. I can build a coil just fine and they both are absolutely great for about 24 hours. At which point the wick under the coil is black and the taste goes from great to awful. I was super happy to finally have a cheap option for atty's but I dont care to rebuild every day. I'm using a provari and adjusting voltage depending on ohms. I drip juice on the wick before test fire. And run em pretty wet. I primarily drip fsusa wyatt earp and copper creek house. 50/50 and 60/40. At first I was using premade coil wick combos from myvaporstore. Then I started rolling 3mm silica and 32 kanthal since I thought the prerolled might be cheap fiberglass. Same issue either way. I dont get it. I drip these juices on be112's and can sometimes get over a month of use with no cleaning or anything. But the norm is probably 2-3 weeks. Anyway please help because I would love to be able to spend pennys for a rebuild rather then like $9 a pop for be112's.
