Not a lot to say about the coils apart from they are some of the best coils i have used. And at the price i paid from ecigone could not go wrng....
These strips are perfect for the Slatra RDA, but outside of that, aren't as good as the VV or NexMesh strips. They're noticeably more flexible than other brands, and warp a bit easier with cotton contact from my experience.
Are they bad? No. I'd recommend picking some up regardless and making your own mind up on these; but I'd go for the alternatives unless you're in love with the Slatra.
They are good mesh coils, Recommend them.
Great value as always
