Hey guys! So I have a clone Uwell Crown that never worked for me, and I went ahead and got an authentic Uwell Crown from Uwell themselves! So on the clone tank, I noticed the coils it came with all have a sharp piece of wire jutting out the side of the head. The authentic coils that came with my authentic crown does not have these sharp wires on the sides. My question here is is it safe to use these knock off coils? Is there any chance of a short or something happening here or am I being too paranoid? Thanks guys!
