Just started reading this thread and i can say that i had the same issues with my ihybrid. I ended up selling it be cause i simply could not get it to work. Funny thing is i had a Zenesis ASH right after that and still could not get it working properly. Come to find out, i had firing issues with both. Sometimes my coil would burn very red and sometimes it didn't glow at all. I sold both of these and just kinda forgot about the whole vaping thing. I now have a Z atty pro and its like night and day. It fires every time and im able to measure out coils and find a good voltage to vape at. Im sold on electronic switches rather than mechanical. Just my 2 cents!
