There is a learning curve for sure. I probably built 25 to 30 coils before I got the good ones I now build. I played around on and off for about 6 months while using other devices. I now have my technique down and can build a coil in minutes. I mainly use mech mods with RBAs now. Hang in there it takes time. By the way Rip Trippers has the best youtube vids on building coils.
