Just wound by first ever Subtank min coil... just so so easy, though ended up with 1.2 Ohm. Gonna love never buying expensive premade heads ever again and have luxury of changing to fresh coil or cotton as often as I want.
Will always carry a remade head around with me in case of emergency
Is it best to dry burn new kanthal coils for a couple of seconds until red ?, not really sure but did it anyway
For the price and whats included in the box you cant really fault the subtank mini, oh and also the flavour & vapour

No wicking issues or leaks, as long as you can see air bubbles rising in the juice you are good to go.
Just refilled mine with some Vaping King raspberry dodgers lovely!
Only downside is how it guzzles juice

Cheers all
