Basically what he said.most digital temp vaporizers is a guesstement......many factors involved.....how hard you draw......how far bud is from heaters.....how dry or wet bud is......its a learning curve for what YOU like.....360 is nice and 400 his heavy vape...but at high temps its easys to combust so you have to practice what you like....like everyone says make sure you are vapeing and not combusting...........I can make it combust at 360 if I hit it hard and heavy..............I Like my silver surfer......1 oclock is about right on it but there again they put em together in colorad and the guy sticks the control knob can be off a little bit so its just a REFERANCE ......not going ot be 1 occlock for everyone.........check you bowl if bud is black you are combusting....after its turns brown reload ...keep you bud you vaped ...called ABV already been vaped and you can make green dragon or whatever out of it or put it in a pipe and smoke it....it will get you high again........thats the bare basics.....practice practice practice LOL
