Not getting vapor in my pulls, I'm a newbie.

I had the same problems with my 901, and still do. There's a lot of things that could be wrong -- I started this thread about it. It might help you too -- lotsa helpful advice.

a few things to check for...
1. battery charged (first charging needs to be bout 7-8hrs)
2. cart filled (put a few drops in-no pooling @the top)
3. atomizer making conection w/battery (I've got a usb passthrough that pushes the center connection of my atomizer further into the body so it won't make a connection with some of my batteries-paperclip again inserted into the center and wiggle/pry it up ever so slightly-you should have 3-4 threads exposed) be gentle.
4.carts shouldn't clog, you're not sucking through the filler material, you're sucking air through the lil slot on the side of the cart.
5. don't cover the lil carb hole on the top of the atomizer with your finger by accident.

hope any of these help, vaping sure isn't as easy as just lighting up a cig, but it's worth it once you get the hang of these quircky lil gizmo's.
