Hello. I have a Smok Stick V8 Baby which I used happily for a span of 3 days until it stopped working. I used it with the T8 coils, which worked well. It worked fine up until it started blinking four times, rather than actually firing when I pressed the button. I have tried swapping coils (I bought a pack of X4 coils which are supposedly better) but this didn't work. I have also tried cleaning the 510 connection with a cotton swab, which also didn't work. I have also charged it fully just to be sure, which still doesn't help. Apparently blinking four times can mean "No atomizer" or "Atomizer short". I have no idea what else I can do, so any help is appreciated.
