Hey guys, I've been playing around with coil building a lot, even tho they work I still build and change daily. Now I've tried most concepts...started liking needle coils that just seat on the wicking reason being if I go for high VG blends afterward just pull wick out burn clean and put the wick back. Now I started trying roller like needle coils just cause it looked cool to me but found that bottom coil usually lacks temp when stacking it up. Think I found a winner with these horizontal ones as they would transfer heat to each other and have equal heat progression because of seating. The ones I have on here are at 0.7ohm and delivers fine from 16W upwards. If you also have a vape/build ratio of 50% like me these are fun to play with. Please do share ideas if you tweak these Vertical Roller Needle coils (as I call em) roller been the conveyor roller idea. Have fun guys.
