Thank you for the pictures. Those give me a very good idea. I think the mini would be the right one for me.
Tell me, is the red a dark red or a bright red?
Also a couple of other questions since I've gotten brave enough to post in this thread, is this an auto or manual feed? This would be my first mod so I hope I'm not asking silly questions. Right now I have manual Joyetech Egos, which I do like but the filling of carts and cartos are time consuming and on the messy side; Although I'm getting better at it.
Last question for the night - do these leak if laid down or thrown in a pocket or purse?
First of all....no such thing as stupid questions.
This is more of a deep christmas red. Not bright, but not maroon either.
These are manual feed...

You put your thumb in the door and push on the bottle and that pushes the juice up a tube and into the bottom of your atomizer. Now, it is possible for it to start auto feeding if you are using a thin juice. Pretty neat once you realize it is happening, but not so handy when your cup overfloweth. These come with a tube reducer that you insert in the bottom of the tube to alleviate this problem. But other than that...no leak issues that I know of.
Wait...that's not true....I am the idiot who was in a hurry and didn't screw the bottle in all the way....next few squeezes was filling the inside of my mini. DOH! I know, lame right? Nothing but a minute or two to clean it up.
I carry mine in my pocket, purse, car cubby, knocked over on my desk, dropped on the floor...and no leak issues.
