Hi Fifty
Take the cart out and have a look at it
One thing I did by accident when I first started was to let my atomizer go dry.
It wasn't a very smart thing as the atomizer cooked itself. Now I top up my cart with nicotine liquid constantly so it doesn't happen.
i don't think the atomizer went dry.....i mean, i just got it in the mail this afternoon, but i don't know....how do i tell, plus i don't have any eliquid just the carts that came with it.
