I got a 5 pack of the 1.2, and a 5 pack of the 0.5 ohm coils. I threw a 1.2 in (I was using the hanna mod) and I like it so far. It seems to like power. I am at 30 watts now, moved it over to the IPV4s . They seem like a good replacement for stock coils. Good flavor, and vapor. Seems to take a bit more juice? Three days of light vaping so far. I use fairly thick 100%vg juice. I water it down a bit to get it to flow well. Im a light weight, so I tend to have more flooding/leaking issues that dry hits. So far its been very good in that respect. As long as I don't put it in my pocket of my coat and shake it around for a few it does not leak at all.
