The Mr. Puffer is a great little box mod also. That's what I'm using until my Big Brother gets here. I have to admit, I like using it with cartos instead of the dripper bottle. I cut out my led and now I have room for a spare carto inside the box! The battery lasts all day, and with two cartos I'm pretty much set. It's very nice to carry all my supplies for the days in the mod. The dripper bottle works great also, I just have a personal preference to cartos.
