Aspire has included more flexibility in the Tigon Kit by including two types of push fit coils. A 0.4ohm DTL style coil designed to run from 23W-28W and a 1.2ohm coil designed to run at 10W-12W more suited to MTL style vaping. Both coils are made from high grade nichrome wire, with great wicking properties for a flavorful vape.
