VooPoo Too- 8 months old. Sometimes now, without replacing the tank or coil, the mod reads- new atomizer y/n? Press either, then it reads resistance correctly and works again. Happens after mod sitting for an hour or so. Just an annoyance, or a safety issue? Minikin Reborn- my fault, I dropped it the other day. No batteries inside at the time. Mod would not turn on for about 30 seconds. Then it started with 5 clicks, and has not had any issues since. Does it have a safety feature that protected it maybe?
