I got a subtank nano today and i must admit this little thing is sexy. Feels nicely made and looks really nice. Im very happy with its ascetics. And it goes nicely on my little ego one i got. But oh dam this think hits my lungs and throat like fire even only with the 1.2 ohm coil! I prepared and got some 0mg nic juice and mixed down my 18 to about 4.5 nic and still. Oh dam. I cant even mouth to lung this thing with out serious burn. The stock ego one tank with the 1.0 ohm coil isnt like this! I dont get it. Whats going on? Sorry im only 3 weeks into vaping.
