So I’ve been a fan of the original crown tank and have used it since it’s inception. I liked it so much I saw no need to get the crown 2, crown 3, or valeyrian tanks. So now Uwell comes out with the Crown 4 and it has my attention. The coils are made of 904l stainless steel, 304 SS, and iron-chromium-aluminum. Well I know nothing about 904 SS or FeCrAl for coil wire. I’m definitely interested so this new tank and it’s coils deserves a thread so we can get real reviews from common folk. It’s pretty new so I doubt many have used it yet but if you do please share your experiences with it and any opinions on these new exotic wired coils.
