So yeah, I will have to agree with everyone about the RSST and what you should get first. However, I'm thinking either way, no matter what you get, whatever is the "first", will be hard as hell. That's my current RSST testimonial. I got it like 3 hours ago. I've been pulling out my hair like crazy. I can't tell you how much mesh and wire I've wasted in that small amount of time. I finally got one put together well giving me a steady 1.8ohm. It vaped awesome, until.. I dropped it. Turned the vamo on, check the ohm resistance, and got 9.9? wth. I checked everything it looked the same, what gives? With tears in my eyes, I took everything apart, and rolled another mesh wick. Then I randomly got the thought to try another atty. Same result. Apparently I tightened the screw down too much and the center contact pin was depressed too far. So took a nail and gently pulled the pin up a bit and my vivi nova worked fine.
Sigh of despair... I keep telling myself that this is worth it, and it's only day one. Note to self: Have oodles of wire and mesh on hand.
PS. Torch the stuffin outta that mesh before you insert it into the wick hole. Then do the pulsing. Has worked for me, on my single successful build...
