Hello guys! So I noticed today a bit of a burnt taste in my Uwell Crown, took apart the tank to see the cotton is a little bit black, not full charred but a but dark. Is it dangerous to continue to use this coil? I may be a week or two until I can get some more coils, I use 0.5 ohm coils with my crown and am honestly iffy about using the 0.25 ohm coils I have with my battery. Would it be alright to continue to use a burnt coil until I can get some new ones? Thanks. Uwell Crown uses japanese cotton and stainless steel coils BTW.
