I've had bad luck with these coils: NI200, kanthal, and SS... I've let them soak for half an hour, primed them like "normal" coils, to no avail. They all taste horrible. I bought the NI200 coils back when you had to import them from China (beginning of this year, maybe?), and bought the SS/kanthal coils from 2 different vendors recently (VaporDNA and MyVaporStore). Has the market been flooded with bad c-cell coils? Are they fake?
The c-cell coil that came with my target tank was amazing, but all my replacements have either not worked at all (NI200 coil that came with the target) or instantly started burning (they seem not to be wicking the juice well at all). I've been mainly using higher-VG juices, but I know these coils work well with just about anything.
I have the same experience after buying packs of TC and non TC cCells. Terrible and I find it incredibly ironic that they actually advertise no dry hits.
