I've been vaping with a spinner for one year. I'm ready to up my experience so I bought the Kanger Topbox Mini kit. I actually meant to get the Subox Mini, but so far I'm happy with my error. I ordered an extra atomizer tank as well. The replacement tank recommended was the Subtank Mini. The Topbox Mini settings require entering what material the coil is made of. The choices are Ni/Ti/Ss/NiCr (NiCr referring to Kanthal). The Topbox kit heads are all marked as such making it easy to know which setting to use. The Subox atomizer heads included are not marked this way, only marked as 0.5 and 1.2 Ohm. I'm want to use the Occ head included with the Subtank Mini atomizer, but am unsure of which setting to enter for it on my Topbox.
