I guess I've never really understood why a sleeper coil is better than a coil made out of two pieces of wire.
People seem to be split if the advantage is better response time or if it's easier to get the two
coils to fire at the same time... but anyway, I know they are a pain to build in my (big-fingered) experience.
They look alright, you might want to squeeze those coil wraps tighter together.
When you're done, tell us how it vapes.
