The t6 coils last the longest, have the best air flow, and flavor production. The only downside is the tightness of the cotton
Good coils and they shjp pretty fast
They work great! Very happy with my purchase
Plenty of cloud with these ; they perform as advertised !
They were purchased as replacement parts, so as yet have not used them. However, the order was received in great shape (no broken or torn packaging), and was in a timely manner! I will definitely be ordering again in the future!!
