I disagree. I use two Flash e Vapors exclusively for nearly a year now with a 1.2mm air intake screw, they are the most silent attys I know, and I know a lot. I just can't get used to anything noisier, and in my ears, the Prime is noisy, for me that's annoying. Everybody says it's quiet and smooth, but for me it's not.
Air is leaking through the top of the AFC-ring. There is an O-ring under the airhole, but not above and metal on metal cannot seal completly as long as you can twist the ring. It's not as bad as on the Berserker, but it leaks. I closed the airslot with tape and could even take a draw. This is something I really dislike, it causes turbulence and takes the draw far from being smooth. I use the 1 or 1.2mm airhole, so the wider holes might not cause a leak, but the tighter ones do.
You won't. And I'm not talkin' anybody out, but these are my points, and for my style of vaping they are valid.
I do trim, and the JC is also open 1 to 1.5 turns depending on the juice. There's no way I could vape the Prime on 22 Watts. Maximum is 14 Watts, 10-12 are better, in TC it's 220°C and 15 Watts. But as I mentioned, I am on the smallest to second smallest airhole, so this might force me to lower the wattage.
All in all it's just not my tank. I'll stay with my FeVs, they are die hard MtL machines and give me just the vape that I want, smooth, quiet, cold vape, dense, flavorful, best throathit I ever experienced. I used to squonk and I owned nearly every M2L squonkatty I could get, but for me nothing compares to a Flash e Vapor.
