I like small box mods myself, I have an AIO I use when I am in bed. Less lumpy if I roll over it. It works really well. I also have 2 Cubis' I like really well. i know folks have gurgle issues, I just work past it and am quite happy. I recently got the eGrip 2, and filled it's tank first time last night. Had it for 2 weeks, with the adapter and a KF3 mini on top of via the adapter as I was enjoying that combo really well. Please use the spiral drip tip. I wish there were more variety of those for bling purposes.
