This problem occurs after not using the eGrip for an hour or so, but I think also at other times. Otherwise it seems OK. I've got the BF SS316-0.5 coil in which came with the mod. I haven't made any adjustments that I know of, so the mod is straight out of the box. It suddenly goes POP! and I get a bit of juice in my mouth - not nice at all. Horrible in fact. Any idea why it does this or how I can fix it or avoid it?
