I used Greensmoke before I found the V4L Vapor King. I did like the huge clouds of vapor with the Greensmoke, but the flavors, battery life, and nic strength selection were not adequate for me. When I got the vapor king, I didn't expect as much smoke, but honestly, I get almost as much. I do notice that, for me, it depends on the flavor. I started with auto as well, but much prefer manual now. ETsmokinandvapin does what I do and draw the vapor in my mouth at first, then I inhale it and get a better throat hit than I ever got with greensmoke. I get the best vapor from tobacco flavors, peach, and grape. I never could get good vapor with raspberry...dunno why. Also, Greensmoke dried me out really, really badly. I have not had that problem since switching. Also juices from a couple of other vendors dried me out...the mix that V4L uses agrees with me best. Anyway, I am lucky that my favorite flavors with V4L give me as much vapor as I got with Greensmoke, but with the added bonus of a throat hit, which I need. Once I tried the Vapor King and Greensmoke at the same time, I never picked my Greensmoke up again, so I sent it back. I hope you have good luck like I have. Also, I've been fortunate that I don't have too much trouble with the prefilled cartomizers. I have had a few that didn't seem to last as long; that could be due to what some people say is underfilling, but it definitely has been few and far between for me. I would never get Greensmoke again for myself. 50 bucks for a replacement battery? Yikes

Oh, and with the manual batteries, I hold the button, wait for the 'sizzle' then draw in the vapor very lightly...I LOVE THEM.

They almost 'feed' you the vapor
