I just got this a couple of weeks ago & I've read the owners manual & luckily got some quick help last time to why after I turn it off, or refill it, something is making it not turn back on. Then I started noticing yesterday that it was beginning to taste burnt. But after only 2 weeks?!? I've had coils in my Aspire nautilus, Cleito, etc that have lasted way over a month before they started tasting funky/burnt. Thankfully this new smok kit came with a spare as I had no idea it would croak out that quickly. Is this normal? Thanks!
