Kangertech Dual Coils Not Working

[xKINGx]

I have a kanger T3D currently, the coils though i usually get new every week but maybe 1 out of these packs actually work? The others have a bad taste or just don't produce much vape. (1.5 btw) Is there another company to get coils for the kanger t3d from or something? Really tired of wasting money on these not working
