The negative leg has a kink, this is intended to make the install as easy as possible and works well, but you still need to be confident in building on UD products. The coils are fused Clapton’s, to make this happen in a tiny space we have gone tiiiny. Each coil has x2 30g KA1 kanthal cores, they are fused together using 38g N80 wire. As a pair they ohm out to 0.4-0.43.
Why the gent? Well single coiled (using the adaptor that comes with the tank) its a real nice sit and chill vape, nice and gentle. A real flavour monster, single or dual coiled.
