Having an issue. I have a aspire cleito tank and aspire pegasus mod. The 0.4 clapton coil was great. Nice strong hit the second I fired it. But after putting the 0.2 clapton coil in, it is so weak. Takes almost 6 seconds to heat up and get any kind of hit. And the hit I get is weak. Anything I am doing wrong? Or is it just how the coil is?
