Hi, I've the Subtank Nano and loving it BUT out of the pack of 1.2 ohm coils I bought X2 of them tasted horrible when used... Yes I did drop plenty of liquid onto them and always leave after filling tank for at least 15 mins. Has there been a problem with them, the taste when they're obviously dud is a horrible sort of metallic taste! Btw, love the 0.5 ohm coil but can't afford to use them as they absolutely rip through my juice!
