I've had a Herakles Plus for about a month, maybe a bit longer. It's always been great. Last few days, it's gotten very harsh. It's hard to explain, but it hurts my throat. I've tried a new coil. .4 Kanthal, (primed) I've completely taken it apart and cleaned it. Different flavors don't help. Once the whole thing is clean, and the coil is replaced, I can't think of any other reason for a problem. It's very odd.
Any ideas?
