I was referring to istick problems in general.Really? It's all over this forum?
I'm here every day, sometimes for hours at a time. I have seen that a very small number of 30w iSticks have had problems.
I also follow this thread Eleaf iStick : part 2 | Page 47 | E-Cigarette Forum and have only read about a few that have had problems.
The istick 50w has had some serious, sometimes dangerous, problems so I would never recommend it to anyone.
