The .4 ohm coil that came on the Cleito lasted me two weeks no problem. I only changed it because my local vape shop was surprised I got that long out of it. Bought a boxed pack of .4 ohm coils for it and the first one is all over the map for the reported ohms on my Coolfire IV Plus mod. Sometimes it will read .4, and I've seen it read as high as 1.5 ohms. Anything over .7 tastes like burnt ass (I assume). I've gotten to the point now where I push the button and check it before taking a pull. Is this normal? I don't remember my first coil doing it, but I never had a reason to check. Anything I can do besides just putting a new coil in? I am going to scratch the sticker thing tonight and check that it's a legit box of coils.
